Been browsing the forums for quite some time now, and decided to finally sign up and pick the brains of people smarter than I...

I have the vx6800 (obviously with Verizon service)

I have applied DCD 3.1.2 and radio 3.39 and everything is working great for the most part. Right after the flash I did *611 to reactive and *228 to reprogram. The data portion came back right away, but I had to call support to get my calls to re authenticate, which they fixed right away.

I use GPS Viewer to get my satellite lock, and then IGO 2006 plus for my nav software.

The only issues I have is that GPS Viewer usually takes aroud 3-5 minutes to get a lock from a cold start. Not a big deal, but would be nice to have faster if there are any tips. I searched and saw a sprint update, that helped those users, and was hoping there is something similar for verizon. The 2nd issue I will do my best to describe...I keep GPS Viewer running in the background all day as it is a pretty light weight program...if it loses it's lock for a long period of time..say when I'm bed...when I try to get a lock the next morning it flashes back and forth from having 5 satellites with no signal whatsoever, to 2 that are locked and back over and over and over again.

If I do a soft reset I am able to get locked again after the 3-5 minute wait. If there is no tips for this, I'm perfectly happy to keep doing as I am, but thought I would ask the experts.

Great Product...thanks a million!!

At the moment there is no update for Verizon because there has been no official GPS software update from them like Sprint. We are working on a fix for other carriers, but it's not going to make it instant like Sprint, instead more consistent initial lock time (between 30-60 seconds).

The gpsOne chip has issues with power saving. It puts itself to sleep so you don't drain your battery with constant use. The problem is that it has issues coming back out, which is why when you soft reset you have to get an initial lock again. I believe, but don't quote me on this, that if you use the power save feature with GpsViewer, that it will keep it from going to sleep, though it will drain your battery very fast.

why isn't this working for me? PRI wont change... my PRL just keeps downgrading.
[Mogul, XV6800 ROM Development] gc14:
Fixed and re-uploaded.
[Mogul, XV6800 ROM Development] studentjunk:
the fixed and updated version works for me. I am still at home so I can't tell a difference yet between the 2.01 version. They both lock 5-6 satellites, and it looks like I am bouncing around the house. But it did update, which is the most important part. Thanks for fixing it.
[Mogul, XV6800 ROM Development] EinsteinTaylor:
I thought I would throw a little more info out there for those developers working on the Verizon update...

As a developer myself(though not in the WM arena), I know that it's much more useful when people provider you with patterns, messages, or generally any bits of information that could be focused in on and repeated as necessary instead of just, "It doesnt work" or "It's really slow"

So...

I seem to have noticed a pattern when using GPS Viewer on DCD 3.1.2 with radio 3.19 (although I would venture it's not limited to those to combinations)

When I first click OpenGPS, GPS Viewer almost instantly sees 7-12 satelites, and gives signal strengths in the 30-40 range, but never locks on. The only way I am able to achieve a lock is to actually leave it on the GPSViewer screen until the power save causes the device to turn the screen off. As soon as I hit the power button and come back on I have a lock on at least 6 satellites. I remember you saying that it has power management problems, and that's what got me looking in this direction for patterns. It's almost like something happens when it goes to sleep that causes the device to suddenly lock on.

Hope that helps some...
[Mogul, XV6800 ROM Development] Osteo:
Or is it sleeping immediately after it gets a lock?.... You could try keeping the screen alive by tapping it occasionally or extending your current screen timeout default and see as I thought the same thing initially (on n2c rom with GPSTest though) and when I extended the timeout for the screen I noted it would lock at just about the time for the screen timeout.
[Mogul, XV6800 ROM Development] EinsteinTaylor:
I can't say for 100% sure that that's not the case...but I don't think so, as I have tried other times tapping on the screen and things to keep the device awake and it just won't get a lock until it has gone to sleep
[Mogul, XV6800 ROM Development] maccaberry:
Anyone got a comment on this?

I live in the US and have had great experience with my internal gps. Locks consistently within 1-2 minutes.

I am now in Australia and for the past 10 days I can see at least 5-6 satellites but cannot get a lock - ever. I dont have any cell coverage here because CDMA doesnt exist here. I am not on Sprint so I dont rely on aGPA anyway.

Can anyone else confirm if they have been able to use the GPS outside of the USA when they have no cell signal.

I have tried radios 3.35, 3.37, 3.39 and 3.42. With and without gc's GPS (QPST) hack. No dice with any combination. Can always see plenty of birds in HTC-GPS Tool but cannot get a lock. I have cleared cache, downloaded ephemeris with quick gps.

Any comments welcome.
[Mogul, XV6800 ROM Development] bedoig:
I've heard similar stories quite a few times. The phones seem to have a hard time getting a lock in significantly different geographic locations, despite the fact that there are satellites in view. How long have you left it sitting with a clear view of the sky?

I'm interested in getting this working as well, since I'll be in Germany later this year. Have you tried using Navizon or WifiFoFum to get a rough position based on local wifi networks (if there are any near you)?
[Mogul, XV6800 ROM Development] Gilliland:
I can confirm just the opposite. I've had exactly the same experience - the Mogul's GPS won't work without some access to a tower. I'm not sure what it needs, but it needs something more than just the GPS data.
[Mogul, XV6800 ROM Development] maccaberry:
I have left it up to half an hour (maybe even longer) with clear sky overhead and at least 5 sats in view and with good signal (greater than 30).

It just looks as if it refuses to lock. I havent tried wififofum yet but used HTC GPS tool and Holux GPS Viewer. I will try wififofum today and see what happens. I have heard it locks quicker than other apps, but that doesnt seem to make any sense since I thought a lock is performed by the gps and its firmware, not the software reading the data coming out of it.
[Mogul, XV6800 ROM Development] gbenj:
it did take a while, but i did get a cold lock without a signal. i had to be in clear view of the sky(which is tough in NYC) but after like 10-15 min with the phone radio turned off, i did get a lock with htc gps tool.
[Mogul, XV6800 ROM Development] jerason:
It's late, but I wanted to share a similar experience with GPS locking and leaving cdma towers before i fall asleep.

I went to Bulgaria, Turkey, and Macedonia and wasn't able to get a single lock.. I would have let it seek all day long but having to deal with their 220 outlets was a pita when trying to charge several devices on top of sharing the adapter.

I left my phone seeking sats for 20-30 minutes, tried quickgps after hooking up to their wifi hoping this would help, but no luck. I tried anything I could think of, but nothing worked.

I will say that while flying I was able to get a lock. I can't recall if I triangulated while we were on the ground and kept GPS up or if I was able to pull a triangulation while we were Mid-Atlantic. I want to say that I was able to start and stop as I know GPS isn't battery friendly and I wanted to skype when I landed.

gps woes

hey guys,

im a long time reader and this is me first post here on the forums.

im having an issue with the gps for the xv6800 on verizon. ive read through lots and lots of posts regarding verizon and their gps service, agps and the like. my problem is that i dont ever get a lock, and never see any satalites in the htc gps tool. it just sits there.

ive got

VZW XV6800

Rom: DCD 3.2.0

Radio: 3.42.30

i installed the radio using the sprint official rom, and then put dcd's over that. im using olipro 2.40 and after i put in dcd's rom, i ran the verizon carrier cab. also the arc mms thing but im sure that has nothing to do with anything other than mms.

my gps settings are

com4

4800 baud

and manage automatically.

location mode is set to on.

i dont have tomtom or another commercial program to test, so ive been trying google maps and windows live. google maps tells me my handset doesnt seem to be compatible with my location, and windows live just tells me gps signal lost.

ive let it sit for roughly an hour and some change, trying for a lock, although that is unpractical for everyday use, i just wanted it to lock.

i read on here that other verizon customers gets theirs to lock in minutes, and that would be great for me if i could get that. so im asking, is it just my handset? or have i not done a crucial step in the flashing, programming?

didnt call verizon when i switched phones to reactivate data or whatever, i didnt know what i was supposed to ask them to do, so i just switched phones thru vzw.com and it makes calls and uses the ## codes perfectly. ive dont the *228 ect .

am i just sol? i really would love to have gps back, my previous phone broke, and i used vznav and that was great.

thanks in advance.
[Mogul, XV6800 ROM Development] 760hacker:
Have you made sure that the the setting for "location on" is correct? I know when i flashed to the latest DCD rom and radio I had to turn Location On instead of 911 only. To do this press the green phone answer button to bring up dial pad then menu then options then move to the services tab then the location setting should be set to Location On for GPS to work properly.
[Mogul, XV6800 ROM Development] kflipproductions:
"didnt call verizon... to reactivate" your data meaning you dont have a data at all? or you dont have a data plan? or you're doing pay as you go?

1) if your phone is blocked from data, GPS wont work

2) if you dont have a data plan and do pay-as-you-go ($2/mb or $0.01/kb), GPS will rack up probably $2000 in charges (my total data usage for my last billing period was over 200mb, and i pretty much only use data for GPS)
[Mogul, XV6800 ROM Development] Soundy106:
It would only do that if you're using Google Maps or another program that actually requires the data connection. Something like Garmin or TomTom, that keeps all its maps locally, doesn't require a data connection.

I just set my phone to Flight Mode - phone, data, bluetooth, all turned off - and within about 20s, GPS Viewer got a lock on 8 satellites and is showing me an HDOP of 1.3 and VDOP of 2.0, which is about what I normally get sitting in my office.
[Mogul, XV6800 ROM Development] kflipproductions:
thats not possible. if your phone is in flight mode, there is now way your gpsOne chip can communicate with satellites, just like there is no way your phone can make or receive calls.
[Mogul, XV6800 ROM Development] kflipproductions:
and if for whatever reason your GPS Viewer is getting fixes on satellites, in flight mode or not, then you should check the settings in your other GPS apps to make sure they are using the correct port (COM4) and baud rate (4800)
[Mogul, XV6800 ROM Development] Soundy106:
Um... I just did it. For something that's not possible, it seems to work pretty well.

There, just did it again: reboot phone (just to ensure everything is cleared), initiate Flight Mode, start GPS Viewer... got 9 birds in about 10 seconds. DOP is 1.3

GPS receivers don't require phone and data networks; they don't need to communicate back to the satellites (some might, for various purposes, but it's not REQUIRED). They only need to RECEIVE the signals from the satellites and calculate the position from there.

Besides, if a phone/data connection is required, I'd like to know how my Magellan GPS knows where it is... it has capability for neither.
[Mogul, XV6800 ROM Development] gbenj:
there are different GPS modes that can be changed in the registry. as far as we know, gpsmode 4 uses assisted gps which needs to communicate with the towers, and doesnt not work on verizon cause we dont have the right ip address for the gps server, but on sprint, thats how gps does it.

if flight mode is on, then maybe gpsmode 4 wouldnt work, but gpsmode 2, which doesnt use the cell tower info, and how vzw phones should be configured, just uses sattelite info, which is independent from the cell phone radio.

because of that reason, gpsmode 2 should work with no cell reception, or even if flight mode is on. ive also tried this, and it did lock. it took a little longer, but it did get a lock within a couple of minutes.

obviously any programs that use data (ie. google maps, MS live search) will be able to give you a gps lock, but wont show any map, cause they cant download them.

as far as i know, gps doesnt send any signals, like a cell radio, it just receives the signals that are already out there.

for that reason, i think using gps(as long as ur on flight mode) on a plane, should still work, and not interfere with the plane or anything.

someone can correct any info i got wrong, but im pretty sure i explained everything correctly. Probably left out the technical details though.
[Mogul, XV6800 ROM Development] 760hacker:
I have used my GPS on a plane with Flight Mode on and it worked and locked on and gave me speed and location. Garmin Mobile. Pretty cool to see we were going about 600mph or more at some points.
[Mogul, XV6800 ROM Development] ezkialrage:
thank you for the reply's!

in response to the data question, i have the unlimited data package for 29.99, so im covered there. the phone dials up evdo whenever something tries to connect to the net and it connects fine.

i only have tried the gps with google maps and windows live search as i dont have tomtom or another commercial nav software.

something i have read is about gps modes, how can i make sure that my phone is in mode 2 instead of 4? is that something i can change? this thread is the first ive read about that.

something to note, i have used the htc gps tool and watched it, i see the satalite dots for a split second when i ciick "open", and then dissapear and never come back. like its trying to work but for some reason turns itself off.

i have made sure that all of my settings are correct multiple times, and have applied the gps fix and even reflashed the radio/rom from an sd card to make sure there were no errors. im at a loss here and i think it just sux verizon locks down their phones so much.
[Mogul, XV6800 ROM Development] Soundy106:
ezkialrage, try GPS Viewer, a freeware GPS program. There's an attachment in this thread: http://xdaforums.com/showthread.php?t=330412
[Mogul, XV6800 ROM Development] ezkialrage:
thank you for that. i installed it and it has been running for about 30 minutes. on the setup screen i see a lot of lines scrolling saying $GPGxxx...1..v..0 ect. on the gps status screen i see all the values at 0 and a big globe wich i rekon would be the earth :) ill let it run until it tries to lock.

also is there a way to check wich gps mode the phone is in?
[Mogul, XV6800 ROM Development] gbenj:
in the HTC GPS tool, when ur on the satellite view, it should say GPSMODE=? whats where the ? is?

as for your sattelite problem, ive had a similar issue before, and its usually solved by one of two things:

1) if you havent already, check and make sure in the phone settings, under the services tab, for "Location Setting" you have location on, and not 911 only. (sorry if youve already done that, i picked up the discussion in the middle)

2) try turning the phone off, take the battery out for like 10-20 seconds, then put it back in and try again

those two are the easy fixes, so try them first, and let us know what happens, if they dont work, then maybe someone more experienced can help you out.

good luck
[Mogul, XV6800 ROM Development] ezkialrage:
i am going to try the battery removal now and see what that will do!

running gtc gps tool in satalite view while its running, i see,

satalites used:0

bullseye target with NSEW directions

Mode 2: fix not available (wich i believe means im in gpsmode2?)

12 vertical rectangles with 0's in the middle and pound signs underneath.

ill keep you posted after the reboot!

and location is on! ive even turned it off, ok'd it and then turned it back on.

update:

no luck on the battery removal option -_- same story as before. i think me phone is just borked. or verry stubborn.

it can make and receive calls and thats good enough for me at the moment
[Mogul, XV6800 ROM Development] gbenj:
so ur saying that ur sure location is on?
[Mogul, XV6800 ROM Development] gbenj:
hmm, not sure that does seem like an odd one. anyone else out there with a solution?
[Mogul, XV6800 ROM Development] serfboreds:
I occasionally get this in a certain area with really poor GPS signal. Make sure you do the following:

Open HTC GPS tool, then choose GPS Port 4, Clear Memory, Open Port, Nav. Initialize. If data is streaming (i.e. $GPGSV,,,T,,,,0,,,,,,*66, etc) then your port should be open and looking. Click on the sat tab and wait. If that doesn't happen, something is wrong (location, External GPS port setting, poor reception, need for restart,

The mode 2 thing is the same, it should say "fix not available" until it sees the birds. You need to be outside with a clear view of the sky in all directions the first time you try to make a connection. It can take a while to lock the first time. Some people say they never can get this to work then try again the next day or later in the evening and get it. Good luck.
[Mogul, XV6800 ROM Development] ezkialrage:
a small update:

i think i go tit to work!

on my way home i was trying the gps viewer again and it actually saw some satelites, they were all red and it didnt say it was using any of them but at least i know their up there :)

thank you for all the help im going to keep messing with it and see what happens!
[Mogul, XV6800 ROM Development] serfboreds:
That is a good sign. Wait for a while and you will have it.
[Mogul, XV6800 ROM Development] gbenj:
yeah, just leave it in a clear view of the sky for as long as possible(make sure to uncheck auto sleep mode. once in a while its taken me 20-30 minutes to get a lock, but it always does lock eventually.

btw, out of curiosity, where are u located?
[Mogul, XV6800 ROM Development] ezkialrage:
i am located in wrigleyville, chicago il. lotsa buildings
[Mogul, XV6800 ROM Development] serfboreds:
This is really one of the things that make a quick lock tough, especially if your provider is anyone but sprint or other with a GPS ROM.

Try to reset your phone and get a lock when you have the clearest view of the sky and you will need fewer birds to get a lock eaach subsequent time.
[Mogul, XV6800 ROM Development] gbenj:
yeah, same with me...i got to school in upstate NY, but im home in NYC for the summer, i dont remember 100%, but i think the latest radio i had when i was still up there was 3.35, it might have been 3.37, not sure.

to this point ive written off the spotty gps performance as a result of the fact that i never(really, never) have an absolutely clear view of the sky.

what i do, with mixed results, is before i leave the house in the morning, leave the gps in the window, whichever has the best view of the sky, for like 10-20 min, and hope it gets a lock. like the previous poster said, once it gets that first lock of the day, the rest are alot easier to get.

I'll see if my gps starts working great in a few weeks when i go to the beach, and then a few weeks later when im back at school, or if GPS and my phone just dont get along.

GPS Location

Do any of you know where the GPS antenna is actually located in the Titan? Does it matter which way the phone is oriented if I can only see sky in one direction? Face Up / Face Down / etc.

Quick QUestion?

First of all thanks for all the help, this forum was really helpful in every which way! especially to not so computer savy individuals such as me!!

Ok....so for my Phone GPS (SPrint MOgul) I downloaded the iNAV iGuidance version 4 (hopefully its a good investment) so far its been a little painful.

I installed it to my PPC. I was able to run it but the GPS info screen would never turn green (it would stay red = I am assuming i am looking for the Lattitude/Longitude since its got numbers but they are in red), the UTC on the screen and LOCAL has all zeroes on it.

So to fix this problem i came back to this site:

the answer was GPS Proxy and by reading on the feedback I liked it (plus it was free - did'nt wanna spend anymore money) so i downloaded that. installed it to my phone (now i have a little blue dot on my main today screen in the bottom right corner)

So after installing GPS proxy i tried to open it up from the Start menu .......that takes me to a screen (Page Menu Start) ........so i clicked on Start.....and thats where it baffles me there is an error message saying " The Garmin Protocol Output extension failed to start: COM port type not specified)..............i dont understand this......first of all i dont have Garmin.....so if somebody could please walk me outta this problem step by step...i will greatly appreciate it!!

Thanks
[Mogul, XV6800 ROM Development] kflipproductions:
hey, you're seeing Garmin because GPSProxy translates the standard GPS data from a COM port to the Garmin Protocol. Before you can use your internal GPS in iGuidance, you need to prime it with something, whether its Google Maps or AstroGPS Launcher(which i never got working.) Also, iGuidance cannot run smoothly on the internal GPS COM 4 port, which is i'm guessing why you are using GPSProxy. GPSGate is recommended, but pricy unless you use some unconventional methods to extend your free trial forever...

make sure that:

your Location is set to 'Location ON'

your External GPS settings are

COM 4​

Baud 4800​

No Hardware Port​

Manage Automatically​

your GPSProxy is set to COM 4 and outputting to COM 2

(not too familiar with GPSProxy, but it sounds like it's intended for Garmin​

you should try running your GPS with Google Maps or LiveSearch first. If you can get your location in Google Maps, then you know you can get it in anything else. if not, then something is wrong. what rom/radio are you using?
[Mogul, XV6800 ROM Development] thugindwnlow1:
ok so i changed the GPS Proxy COM port: COM 4 and output COM port: COM 2

still the same garmin error message!!!

i am using

ROM version: 3.35.651.2

Radio version: 3.34.04
[Mogul, XV6800 ROM Development] kflipproductions:
so you are using the official sprint rom? you should try loading a custom rom from DCD. you'll have to read around to see if you can just load the official sprint rom and be good to go, i have vzw so there were more steps for me but i had fantastic results. also, like i said, GPSProxy is designed to specifically translate the information from your GPS Port to the Garmin Protocol, so thats most likely why you are receiving that message. did you try google maps? its free www.google.com/gmm
[Mogul, XV6800 ROM Development] gbenj:
for some reason im getting a couple of issues with the newest release of google maps. i think its 2.1.0.10, but it wont load anything, when: a)once the GPS gets turned on, b) if the wifi switch is on.

even if its not connected to wifi, it will still try and use it, if the switch is on(like when running navizon)

also, the data will be fine, until i click Use GPS, then the program needs to be restarted to get it to load data again.

anyone having this problem? i think im gonna go back to an older release,

but does anyone know where the google maps registry keys are located? theres gotta be something in there that can be adjusted to get it to work...

thanks
