Just to clarify, the first lock after a ROM flash has taken me anywhere from 2-5 minutes.

im on sprint using the new 3.35 rom my app is gps today i live in wny i get 4 satts minimum inside my house and 9 min outside both scenarios i get a lock in under a minute

VZW user in Central MN... On my first boot with DCD 3.0.0 I acquired a fix (6-8 sats.) in about 20-30 secs using Google maps.
[Mogul, XV6800 ROM Development] orlandojumpoff:
just the new sprint rom
[Mogul, XV6800 ROM Development] orlandojumpoff:
When i first updated to the new rom i had the same problem tho... gps wasnt working.. i had to reinstall due to some other problems and it started working right away (thank gopdness). So maybe something went wrong during your installation? Also be sure to let the sprint customization take place after the install.

Been traveling in St Louis, Old DCD rom would lock in 1-2 minutes and never in the house. 1st time I fired up GPS w/ DCD's 3.0.0 I locked on in seconds inside my hotel room. I have Sprint.:)

Columbia, SC - VZW 6800 -

Radio 3.27 - DCD 2.32

I was acquiring signal in about 2 - 3 minutes with TomTom, Garmin XT and IGO and longer on first boot. Need a GPS launcher to get GPS to work.

Radio 3.35 - DCD 3.0

I'm acquiring signal in about 10 - 20 seconds with Garmin XT (don't use others now) and do not need a GPS Launcher.

It get more sats now (about 8 to 11) and seems to be off more to my location. Although I would really need another GPS to make sure. I think Garmin's maps are not as good as Tom Tom or IGO. I don't think it's the gps, but more the map I am using.
[Mogul, XV6800 ROM Development] Keystone:
As I noted in the GPS FAQ with two Titans, side-by-side running identicals ROMs and images, one could regularly lock-on to and hold multiple satelites within 30 seconds while the other unit would be lucky to get a lock onto one or two satelites within 30 minutes and then would lose a lock within minutes. That experiment has been repeated with identical results today with the the latest radio and DCD 3.0.1 on both units, side-by-side indoors and outdoors.

There is likely a hardware discrepency amongst Titans. It's unlikely to be software or user error and just luck of the draw as to how GPS efficient your particular unit is.
[Mogul, XV6800 ROM Development] JerrytheGreat:
Update--it must be a combination of device and geography:

On my Alltel 6800 with DCD 3.0.1:

Went to Orlando, FL today--got 7+ sats immediately, locked in 10 seconds, repeated

Drove throught Tampa, FL --got 4+sats, locked in 20 seconds, then swerved and stopped playing

Got to Sarasota, FL 1 sat, no lock.
[Mogul, XV6800 ROM Development] Keystone:
Weather too as heavy overcast will have an effect. This will be particularly true wth those units that already have issues with weak reception and difficulties locking on. For them, clear days may give passable results but with heavy clouds, nada.

[Mogul, XV6800 ROM Development] billcohen:
Alltel in Tucson, AZ

Takes 5-10 min for a lock and accuracy can pretty bad. I have seen it off as much as 100 yards; often the location marker moves off of the street. Refresh also seems to be slow. Between the inaccurate reading and slow refresh, it is not practical.

[Mogul, XV6800 ROM Development] kain144000:
Hey, my probs not w/ the GPS locking, but w/ it being buggy and not waking up /reinitiating upon device waking from standby. Or, at least GPS Test no longer updates data. Sometimes no change from "GPS Starting Up". Is it the s/w, driver, unit, or ROM(s) (stock v3.35, DCD's and no2chem's v.3.35-based ROMs)? I believe it worked fine w/ the leaked v3.16. BTW, this doesn't happen all of the time, but once it does happen, I have to soft reset.
[Mogul, XV6800 ROM Development] rawr:
Telus - Toronto, Canada

locks about as quickly as my Holux M1000 BT puck does but it's not as accurate. Sometimes it'll be a kilometre or 2 off in any app I use. iGuidance 4.0 requires that I tap the screen periodically to update it.
[Mogul, XV6800 ROM Development] rschell:
I have similar standby issues, GPS works fine until the phone is in standby for a period. Then I have to soft reset to get GPS to work again. Tried GPSGate, it helped some, but problem still exists. Any app to reset the GPS hardware?
[Mogul, XV6800 ROM Development] chong67:
I have similiar problem also.

I cant get my GPS to wake up from standby.

I go to google map and it cant find my GPS.

Then I use those AstroGPSLauncher to lauch my iGuidance and my GPSGate turn ON, then I can pretty much do what I want.

I dont know how to turn on my GPSGate.

I must be having a similar issue with GPS not coming out of standby mode or something. I'm using GPSToday today plugin. When I have issues, it doesn't seem to be able to open the GPS connection at all.
[Mogul, XV6800 ROM Development] dizwayney:
I'm just wondering if those that have the problem getting a lock have tried downgrading to the stock rom and then reflashing with new radio and DCD's latest. A buddy of mine couldn't get a lock after flashing with 3.27 DCD 2.32. We upgraded him to 3.35 and DCD 3.01 and still no lock. We followed the instructions here: http://xdaforums.com/showthread.php?t=376873

and took him back to stock, then reflashed directly to 3.35 and DCD 3.01 and yareeka, the GPS is now locking within 1 - 2 minutes in Google Maps. I don't know if this will work for everyone but I wanted to confirm that this did work for us. He has a Verizon 6800 by the way.
[Mogul, XV6800 ROM Development] gman16000:
VZW 6800. Flashed with 3.35 and then 3.0.1. Everything works but I never (>10 minutes outside) get a GPS lock in Google or MSN.

Is there a config that needed? Like settings->Phone->Location Services (which I have turned on)

Any other procedure that anyone had luck with? (like a hard reset)

I love the 3.0.1 Rom but I really wanted the GPS.
[Mogul, XV6800 ROM Development] j-squared:
I did this by accident because i buggered up the original flash of the 3.0.0 ROm (my fault). Went back to stock ROM on Verizon - went directly to 3.0.0 (I added in the MMS myself and only one minor reg tweek) and this is a very stable phone now and I get a lock quite easily. I do use GPS Viewer to get the GPS up and running - then TomTom, Google, Yahoo or Microsoft Live all find the GPS rather quickly - (1-2 minutes).

[Mogul, XV6800 ROM Development] bakntyme:
First, you have a Titan, not a TyTn. They may be pronounced the same but are different devices.

Second, I emailed iGuidance technical support about this issue. Their responses were that iGuidance is not compatible with the serial port mapping of the HTC GPS driver, and that they would not be modifying iGuidance to be compatible, as their expertise is only in writing GPS software. They suggested using GPSgate or the equivalent.
[Mogul, XV6800 ROM Development] dizwayney:
I use BAF's GPSLauncher to launch TomTom, and it works everytime. Satellites die out when I get a phone call so I have to restart TomTom but other then that, it seems like a breeze compared to what you're going through.
[Mogul, XV6800 ROM Development] dsiminiuk:
I think I read your thread about that somewhere but it just doesn't make sense that v3 works perfectly and v4 does not. If they are only concerned with the GPS software itself then why would the serial interfaces have changed? I know, I know! Makes no sense.

I also tried the GPS Viewer 1.0 as the middle ware and it works just as well as GPSMeterPE or Google Maps at starting up the GPS. In fact there is a button for it so you have full (manual) control.

I understand from previous writings that the Astro GPS Launcher also starts TomTom so maybe I'll give that a trial and see how it goes and how the features stack up to iGuidance.

Thanks for the replies...
[Mogul, XV6800 ROM Development] bakntyme:
Must have been someone else's thread, I think this is my first post on this issue, but at my age I no longer remember things...hence my total reliance on the calendar in my Mogul.. I actually emailed iGuidance about this problem with v3, and they confirmed it as a problem with v3 and told me it was not fixed in v4. Have you gotten v3 to work properly?
[Mogul, XV6800 ROM Development] rschell:
Google Maps and GPS

May be a workaround on the resuming after standby issue, is to make sure that you close down your GPS communication before going to standby.

With Google Maps, I de-select "use GPS", exit Google Maps, then put the phone in standby. The times I have done this, coming out of standby Google Maps seams to recover, slowly (in effect a warm/cold boot of the GPS) but it doesn't seam to lock up. Try it and see if I'm right that the driver/hardware just does not recover from a abrupt shutdown. Doesn't help the phone call issue, but might get someone pointed in a fruitful direction.

On a side note, I have observed that just activating GPS causes about a 100 mA increase in current drain, then with Google Maps downloading map data that causes an addtional 100-150 mA average drain. So when your using your GPS and Google Maps, the phone is drawing 350 to 400 mA average. Don't expect the battery to last very long. Ymmv, using card based map data will drop you to 200 to 250 mA, but that is still a large current draw.
[Mogul, XV6800 ROM Development] dsiminiuk:
Yes, I had no trouble with v3 using the Astro GPS Launcher. No joy with the same setup on v4, hence the essay above.

I am trying TomTom 6 and tracking works fine with just the Astro GPS Launcher but I noticed that some of the same problems exist with stale map data. I did not have a chance to check the map data on iGuidance v4 before I dumped it for the TomTom test. I'll have to see if I can find updated maps for TomTom.

And TomTom 6 does not speak the street names as iG v4 does but I like the add-on voices you can drop in. Yoda tells me to "turn in 300 yards you will". What a hoot.

I like TomToms ability to prompt you if you want to use toll roads when you select a destination rather than it being a configuration choice one way or the other as in iG. If I can get updated maps I may just stick with TT. It seems a little more friendly on the interface GUI.

In both Chicago and Boston it takes 3-4 minutes to get a lock using GPS Viewer, Google Maps, or TomTom. I do have QuickGPS installed, but due to the lengthy lock time, I don't know that it's making a difference.
[Mogul, XV6800 ROM Development] kcmoney13:
Wizzy,

I am having the same issues as you, running the same setup with a verizon phone and DCD 3.0.1. Its really hit or miss though most of the time it takes a couple minutes to connect sometimes 4 to 5. but every once in a while it will connect right away. Anyone else figured out a configuration that connects often?
[Mogul, XV6800 ROM Development] kottoson:
I have been using iGuidance 4.0 ever since DCD released ROM 2.0.x which enabled GPS. There is quite a bit of information in the thread

http://xdaforums.com/showthread.php?t=363431.

Especially the first 6 posts. On post 4, there is detailed information on how to make iGuidance 4.0 work with the GPS. I use Franson GPSGate 2.6.0.304 (map GPS port COM4 to a Virtual COM Port / NMEA (COM2)) and the MortScript iGuidanceInternalGPSLauncher.mscr. This script adjusts the backlighting and start iGuidance using AstroGPSLauncher.

iGuidance 4.0 works real well using this method and is pretty simple to start and shut down. GPSGate has options to suspend the GPS receiver when not in use by an application or when the device suspends so the GPS receiver is drawing power only when needed. When iGuidance is started, I get GPS lock within 30 seconds when outside or in my car. It usually takes me that much time to get seated and my seatbelt buckled. It tracks very accurately.

I'm wondering whether there are different hardware versions out there?

My GPS (Sprint) is amazing. It'll get a 7 satellite fix in the middle of the house in the basement in about 20 seconds, or a cold fix outside in around 10 seconds.

Perhaps HTC changed something in the design at one point?
[Mogul, XV6800 ROM Development] Keystone:
Yup, that's a possibility after I've tested two units side-by-side with identical software set-ups. Either different revisions, poor quality control, or fragility in how the antenna is designed, etc..

There is certainly a hardware discrepancy between Titans, and I think much of people's poor GPS performance is the result.
[Mogul, XV6800 ROM Development] dagurasu:
I need to read many more of the hundreds of pages on this cause I've been busy, but this is not entirely the whole story. The unoficial rom did not come with qgps. TaylnOne's post had links to a version that worked with the mogul and with that, the unoficial rom worked pretty well for me. It would always lock in a few seconds... except, sometimes it froze up and there were problems when sleeping the device while operating gps. The thing was most of these

problems were at least obvious and one could soft reset and be going again.

On the new rom.. locks are sometimes in 15 seconds, sometimes in

minutes, and once or twice I've even found where gpsviewer failed to

scan.. so it is very sporadic. Worse, it is usaully not too obvious how

long one will have to wait, so you wait a couple of minutes before

realizing that a reset will help you. I have found that using gps viewer and monitoring the behavior of the data streaming in, I can usually tell if it is going to lock or not but that's a nuisance. There is something very different about when it's working well (ie 15 seconds) or poorly (several minutes, to possibly not at all), ie how fast it's scanning through satelites(if at all) and the amount of data streaming in. This did NOT happen with the unofficial rom. I don't see why locks should take 2 minutes if outdoors and qgps did it's thing correctly. It should be pretty instant since it should already know where the sats are. It is supposedly downloading sat locations that is what takes time and qgps should solve that.

I'm not actually using stock though, I'm using dcd 3.0.something with the new stock radio, but from what I can tell results are the same. One caveat, I had reg settings from taylnone's post for the leaked rom's qgps and accidently copied them back in over the new rom. Maybe I should find the official reg settings again for this rom, but I don't really believe that's causing a problem.

GPS in Mogul

on Sprint in san diego, CA. using BAF's GPS toggle Today plugin- starts ANY mapping software, googlemaps, live search with a lock. I can toggle gps on, and by the time iGO maps opens up, its got 5-12 sats for me. sounds like a lot of you need the ability to prime the gps; well thats what BAF's gps toggle does...and does it very well.
[Mogul, XV6800 ROM Development] dagurasu:
Many of us are happy with google maps. google maps does not require "priming" in this sense and is not helped by it. However everything requires knowing where the satellites are. That's what QGPS is for, to download this data rather than wait to receive it slowly from the sats themselves. I'm fairly certain that BAF's does not do that. Also gps viewer does not require "priming" in the BAF's sense. I think it's a safe bet that if it will not work(and it sometimes won't), nothing will (although as I say this I'm reading about $GPGGA vvs $GPRMC data because sometimes I see GPGGA position data when gps viewer is not indicating a lock, unfortunately I cannot see the whole "sentence" in the gps viewer window to interpret the data). I assumed I had the sleep while acquiring bug, but I've been watching carefully recently and I'm pretty sure this is not my main problem either.

People who need "priming" in the BAF's sense and who do not realize it are probably having a very hard time to ever get GPS to work at all. This is different from those of us for whom it works poorly or buggy.

Verizon Wireless XV6800 w/DCD 3.0.1 & 3.35.4 radio.

It seems spotty. Sometimes I can get a lock sitting by the window, sometimes I can't. If I do it is 4-7 satellites. The accuracy once it has a lock is usually within 15-20 feet.

Getting the initial lock if I haven't run google maps or Live Search for a while sometimes takes up to 10 minutes (even if QuickGPS is running), but subsequential locks after that are instant or up to 15 seconds.
[Mogul, XV6800 ROM Development] gbenj:
mines pretty much the same way. using the same setup as you...(xv6800, dcd 3.0.1) did you mean 3.0.1? since as fasr as i know there is no 3.02, or 3.0.2...etc?

sometimes it works great, takes like 2 minutes, sometimes it wont for a day or so, and if i dont really need it, no big deal but when i do...man do i get frustrated. i hope i dont chuck the thing across the street one day when it stops, and i need it.

i would love if people came up with a list of troubleshooting that usually helps them resolve their issues, especially for us who dont "officially" have gps

thanks
[Mogul, XV6800 ROM Development] aph:
Have had numerous GPS issues with dcd 3.0.1. After a hard reset, the phone always gets a lock but the next day it will stop working. Without installing anything or making any changes. Going to nueROM now for the first time since 6.1 went official. Will report back.
[Mogul, XV6800 ROM Development] dagurasu:
Are you with sprint? Have you tried the 3.35 stock ROM? I'd like to hear from anyone who has used both. My problems seem similar to yours, except maybe because I've had real need of alot gps use recently, I may have managed to run into the annoyances a bit more, and been more annoyed by them. That said, it has been very useful to have. Also I assume you mean soft reset.
[Mogul, XV6800 ROM Development] scorp508:
Yes, I did mean 3.0.1, sorry for the fat finger. I'll go correct it.

Last night Google Maps said "GPS active", but had 0 sats acquired even though the location dot showed me being across the street about 200 yards instead of sitting in my living room when the other day it had great accuracy and 7 sats locked in. The skies were very overcast here in the Boston area last night, that may have been part of it.
[Mogul, XV6800 ROM Development] gc14:
Since upgrading to a custom 3.0.1 rom with the new radio my gps has been working flawlessly for me. I follow a precise method that works for me everytime.

1. Make sure data connection is active and start QuickGPS. There's a time at the bottom that tells you how long the data is active for. I download the data over and over until it says 7 days at the bottom. Once it says 7 days I exit QuickGPS. I then go into task manager and make sure QuickGPS is stopped.

2. I open Holux GPS Viewer and make sure it's set to Com 4/4800 baud, and then open the gps. Immediately after opening I check the WAAS checkbox and immediately after checking the box, I click Cold Start. I then minimize GPS Viewer (I do not close it in task manager).

3. I then open Google Maps, GPSToday, or whatever software I feel like using at the time and run it normally. For Google Maps I click Use GPS...for GPSToday I put it in persistent mode by sliding the box to the right. Once I get a lock, I then minimize the program and close GPS Viewer in the task manager.

Using this method gets me a fix anywhere between 5 seconds and 1 minute every time I do it flawlessly. I know it seems like a lot to do every time, but really it just seems like it...I can do the whole process in under 30 seconds.

Also, if you follow these steps and say you want to stop...do not just close the program...make SURE you stop the gps first. For instance, in Google Maps click Use GPS again to uncheck it and turn it off. In GPSToday click on the left softkey and choose Run GPS to turn it off. Then you can close your program.

If you follow the steps once, and use the GPS for a little, then stop...but then decide you want to use it again shortly after, you don't need to do steps 1 or 2. Only if you've stopped for a while and the GPS needs to be woken up.

scorp is also right. The gps will work better with clear skies...I too am in Boston and it was ****ty last night, and ****ty again today, and it's taken a little longer for the first fix, but it's still quick and consistent. Be patient. :D

As always....YMMV
[Mogul, XV6800 ROM Development] dagurasu:
QGPS usually says 6 days and 23 hours(and who knows how many minutes) after a download. Maybe there is some timing instability where if the screen updates just right or you grab the update just right within it's refresh cycle or the download box closes just fast enough or whatever and it hits a full seven days, but I seriously cannot imagine this has anything to do with anything. If you have just downloaded the data then it should be fresh enough. I think there is a lot of voodoo about something worked a few times for someone and it becomes truth. More likely the system is unstable and you got lucky or unlucky a few times. I mean no offense, when I try some voodoo and it works for me, I may keep doing it too.

All that said, I do wonder if the data is really good for 7 days. Some places say this data shouldn't be used more than half an hour. So it may in fact help to run qgps more often than what it does automatically, but I've played with that too, and I am not yet convinced this helps at all either, it certainly doesn't "work every time".. but maybe I should have waited for the magic seven.
