Ok, maybe I've not been clear here - I'm not wanting to swap ROM stories or compare radios, I'm asking if anyone else is experiencing severe GPS problems with the stock ROM, and stock radio.

Anyone?

This isn't "which ROM/radio is best for GPS", it's "did the HTC ROM break your GPS?"
[Tilt, TyTN II, MDA Vario III General] livefastdiefun87:
I have never looked at the official HTC ROM for comparison but I had the same thing after updating to certain ROM (non-official) the only way around it I found (other than replacing the phone) is another radio. Its not a problem with the ROM at all my good man just replace the radio and you should see a quicker lock time :)

I use radio 1.64.08.21 ang get a lock after approx 10-15 secs
[Tilt, TyTN II, MDA Vario III General] JimmyMcGee:
Well If you are going to be snippy about it. Never mind. Forget I tried to help.

Though You may be hard pressed to find someone who is using the Stock ROM, I believe most people are wooed by the magic of Leo26, ConfusedStu, dutty, and the other Chefs out there.
[Tilt, TyTN II, MDA Vario III General] Boinng:
So you wouldn't say that quoting my post back to me as "...snip snippity snip snip..." was being "snippy" in the first place?

I'm not trying to pick a fight here, I'm just interested in whether this is a common problem or not. I know GPS performance varies between radios, but with this new ROM & radio the difference is pretty shocking, and given that HTC are expecting the whole world to have installed it, I was surprised nobody else seemed to have noticed. You're probably right, nobody here kept it for long enough to find out apart from me, but I like my phone to be "stock". I guess this is my reward.

The answer probably is to try another radio, but it's a funny old situation.
[Tilt, TyTN II, MDA Vario III General] Rumball:
I'm using the new (WM6.1) stock ROM from HTC on my Tytn-II and haven't had any issues with GPS lock. I would say less than 30 seconds assumming it has a clear view of a good percentage of the sky. Fix time is the same whether I use TomTom, GPS Tuner, or the HTC-GPS Tool.

Ofcourse if I try and start-up GPS while indoors or in an area where buildings block more than 50% of the sky then the fix time can be much longer.
[Tilt, TyTN II, MDA Vario III General] kavi:
I had the same problem after loading the 3.28 Hard-SPL. Reverted back to stock SPL and GPS is lightening fast.

Are you using the stock 3.28 SPL or the new 3.28 Hard-SPL?

Did you run Kaiser Tweak? if you did I would Hard Reset and try GPS test.
[Tilt, TyTN II, MDA Vario III General] ardsar:
Got exactly the same problemwith the htc stock 6.1 rom. Nothin to do with hard spl etc as neve used it - phone has always been htc branded.

it appears that although quick gps data is downloaded, it is not used hence taking a long time as it needs to download the almanac data frim the satelites instead of quickgps. Ive emailed htc, but i have NEVER had a reply to any questions ive a ked in the past.
[Tilt, TyTN II, MDA Vario III General] Boinng:
I'm on the stock SPL - my phone is Vodafone branded so I was originally using Hard SPL (with which I flashed the original stock HTC Rom) and then flashed the HTC 3.28 SPL after I found I had freezing issues with the 6.1 update. Haven't touched the new Hard 3.28, but from what you say it's obviously not going to help. I did wonder if the mystery fix in the 3.29 SPL might have something to do with the GPS, but if it's working fine for you on 3.28 who knows.
[Tilt, TyTN II, MDA Vario III General] Boinng:
That's how it looks to me too - looking at the signal levels in GPS Test etc, it's not obviously a problem with the radio performance itself, which makes me doubt that changing the radio will actually help (while it will no doubt screw something else up).
[Tilt, TyTN II, MDA Vario III General] Boinng:
I was just browsing through an interesting thread here - http://xdaforums.com/showthread.php?t=292178 - on how Quick GPS works (or didn't work for a while) on the Artemis. There's some interesting stuff there about how all this is supposed to work.

I'm really suspecting that Quick GPS is broken in some way in the latest ROM. If it were working, then the phone should always have the almanac data and this should be visible in the settings screens in Tom Tom and other gps progs as satellites it's expecting to be there, but for me - unless I've had a very recent lock - it's always blank. In other words, the data isn't there, regardless of what Quick GPS is saying.

And a good question would be - where should the data be? Quick GPS itself is stored in the \windows folder, but there's no sign of the "packedephemeris.ee" file mentioned in the Artemis thread. Does anyone know where we should be able to find it on the Kaiser?

Another question is what server(s) should Quick GPS be downloading from - in my non-functioning Quick GPS, the settings in the registry are as follows:

HKLM\\SOFTWARE\HTC\QuickGPS\0\0\IP > xtra1.gpsonextra.net

HKLM\\SOFTWARE\HTC\QuickGPS\0\1\IP > xtra2.gpsonextra.net

HKLM\\SOFTWARE\HTC\QuickGPS\1\0\IP > xtra3.gpsonextra.net

HKLM\\SOFTWARE\HTC\QuickGPS\1\1\IP > xtra1.gpsonextra.net

HKLM\\SOFTWARE\HTC\QuickGPS\2\0\IP > xtra2.gpsonextra.net

HKLM\\SOFTWARE\HTC\QuickGPS\2\1\IP > xtra3.gpsonextra.net

The three servers (xtra1, xtra2, etc) are also listed under HKLM\\SOFTWARE\HTC\QuickGPS\SNTP as Server 1, Server 2, Server 3 - does anyone see anything different on there working model?
[Tilt, TyTN II, MDA Vario III General] Sideburnt:
Im having the same problem,

Running Dutty's 6.1 Dual rom. Once the ROM had installed I noticed that QuickGPS didn't work straight off the bat. I suffered long GPS lock wait times. I found a QuickGPS cab file which fixed QuickGPS but my lock times don't seem to have improved. Via GPSTest I get 3-4 within sight straight away, but they sit on red for ages perhaps a few more satellites with appear but again they'll all sit on red. until about 15 mins passes, then finally a fix.

Im sure my GPS responded quicker than that in previous ROM's. at the moment its not really effecting me and im really not going to go through another ROM change again to test.

Im already on radio 1.64.08.21 which is supposed to be the best out there. tut.

no idea about hard spl and all that business, not really sure what y'going on about.

Would also like to find a fix for this, as i've tried a few different methods of fixing with no luck.
[Tilt, TyTN II, MDA Vario III General] Boinng:
So it's not the radio, which ties in with my hunch that this is more to do with Quick GPS. But my Quick GPS registry settings match those I've found elsewhere, and I've found the data - it's an "xtra.bin" file in the Windows folder, which also matches reports from working installs. And I'm having no problem with the whole downloading process, that's happening in the background (through Activesync) just as it always was.

So is there something in the actual Rom (and presumably the base rom used by Dutty) which isn't picking up that data when utlising GPS?
[Tilt, TyTN II, MDA Vario III General] Sideburnt:
Well I think I read a few posts on Dutty's Dual ROM thread about QuickGPS not working straight off, but its a long thread to plow through to find out. S its entirely possible there's a good reason.

Hmmm
[Tilt, TyTN II, MDA Vario III General] Sideburnt:
well I proved to myself im not inherently lazy I did a bit of searching around and found this little gem of a thread

http://xdaforums.com/showthread.php?t=375172

it suggested that QuickGPS has a region setting in the registry

low and behold I checked my

HKLM\Software\HTC\QuickGPS\region

and it was set to US,

I changed this to say UK, I've not tested this but I think this might make a difference. I'll let you know whenI get the chance to play around on the way home from work. I usually try and get a fix on the 15 minute walk to my bus and dont get any fix at all, If all goes fine I'll be watching myself in Igo8 on the way home. Sad.
[Tilt, TyTN II, MDA Vario III General] Boinng:
Hmm, fingers crossed for you, I just checked and mine it's showing "GB" though. So maybe your's should be GB (although that's not working too well for me) or maybe mine's wrong, and should be UK?
[Tilt, TyTN II, MDA Vario III General] Sideburnt:
well I just popped outside for a quick test and Corblimey guvenor if Im not getting a fix in about 20 seconds.

Which is excellent to say the least since i was sat under a canopy of trees at the time and its grim as normal up't'north.

Id switch yours to UK, I didnt really think to try GB, but If its not working for you right now, I'd suggest trying UK.
[Tilt, TyTN II, MDA Vario III General] Boinng:
I changed it to UK, soft reset, tried Tom Tom, no change. I then checked the registry and it had switched back to GB, so I changed it again, closed and reopened Quick GPS and redownloaded, back to Tom Tom again and.. no change. I don't think it's going to do it for me, maybe we have two different problems here..
[Tilt, TyTN II, MDA Vario III General] :
no problems with GPS on cold-start.. using RomEOS w/no the same start-up time. Maybe a little quicker...

Hello all, I'm new to the board, but not to PPC's, although i'm only an "enthusiastic amateur"! :), so talk of cooked roms makes me just think of food! :p

I've been having similar GPS problems since updating my Orange Tytn II to 6.1 a few weeks ago (the official ROM) and had tried many things suggested in this thread and others.

The one that worked for me was using "GPS Quick Position" instead of "QuickGPS"....found in this thread...

http://xdaforums.com/showthread.php?t=336599

Since using this, my GPS fix times in TomTom 7 have returned to 8-15 seconds rather than several minutes before (even through my Citroen's funny windscreen! Athermic i think they call it!)

Try it...hopefully will work for you too.

For some reason when I try using the Quick GPS software, I get told the data can't be downloaded or there was a send error when trying to run it. I also found that I no longer had a Wi-Fi icon in my settings until I uninstalled it and did a soft-reset.

Running a stock tilt with the 6.1 AT&T update, bloatware not-installed.
[Tilt, TyTN II, MDA Vario III General] sys50000:
Quickgps region is essential. NL is wrong.

The region in the registry settings for Quickgps does make a difference.

I did this test inside the house:

- change region to NL

- download quickgps

- start GPStest 1.04

Waited 1 minute: no satelites

- change region to BE (or DE)

- download quickgps

- start GPStest 1.04

Waited 1 minute: Satelites in red all over the place. They slowly disappear one by one, but undoubtedly quickgps info was used.

Conclusion: NL is not a valid region to download gps data for. BE and DE are. You should check if your region code is supported, otherwise use a neighbor country.

Same Gps Problem

I May Be Alittle Late Responding, But I Have The Same Gps Problem After 6.1 Upgrade...it Drives Me Crazy And I Don't Know How To Fix It. Pre Update-my Gps Was Fast And Since, Can't Use It At All...takes Too Long. I'm Getting 6-8 Satellites, But No Gps. It's Usually .5 Mile To 1 Mile Off. Any Direction Or Instruction Appreciated.
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
You could do what I've done which will definitely fix the problem - complain to HTC or whoever provided the phone/WM 6.1 'upgrade' telling them their upgrade is unfit for purpose and get it reverted back to WM 6.0 under your warranty. I had this done by the HTC repair centre here in the UK for free. Whatever you do, make sure you complain to the provider about it.
[Tilt, TyTN II, MDA Vario III General] Barneyabz:
Really depends on the radio rom and when you upgraded. HTC first 6.1 rom upgrade had the problem. However they replaced it a month later (or two) with another version which has helped resolve the problem (not completely but now at least I get fix in around a minute). The new radio verison is 1.65.17.56 - check yours and if its not that then upgrade the rom again and see if that helps.

I had problems with the new Stock wm6.1 rom, but after i put my phone for a minute outside on a free field it found satelites and since then its working perfectly
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
WM 6.0 original still far better for GPS than WM 6.1 with 1.65.17.56 radio

If thats referring to my post, yes I know all about the 'sneaked through' radio update (I think I even informed people about it here myself earlier in the thread) but although 1.65.17.56 is better than 1.65.16.25 for GPS fix times in the UK, it's still far short of what I'm achieving with my Windows Mobile 6.0 reverted TyTN II. When they truely fix the GPS (perhaps by including this well reported 1.71xxxxx version radio?) then I'll watch for the feedback as far as GPS is concerned and may upgrade then but at the moment the pitfalls with the official HTC TyTN II WM 6.1 WWE (UK Release) 'upgrade' outweigh the advantages for me so it's staying as-is!
[Tilt, TyTN II, MDA Vario III General] iRAY:
I was experiencing same issue after upgrading my Tytn II to official WM 6.1 CSY. I tried some different radios but no luck.

Few days ago I found, that there is available 1.70.18.02 radio from Dutch ROM. I didn't expect it can solve anything (because 1.71.09.01 eMonster does not help), but I noticed it uses same protocol (25.83.40.02) as HTC WM 6.1 CSY and WWE (I was running: RUU_Kaiser_HTC_CSY_3.28.462.1_radio_sign_25.83.40.02_1.65.17).

Well I installed Hard SPL 3.28 and 1.70.18.02 radio and all start to work like a charm :) Hope it helps.
[Tilt, TyTN II, MDA Vario III General] rytomi:
I'm using the Stock AT&T 6.1 ROM on my tilt. I've noticed the GPS lock time is severly skewed by how old the Quick GPS data is.

On my tilt, if the Quick GPS data is about 3 days old, then it takes about 3-5 minutes for a lock. If I just updated it, it will lock almost immediately (less than 15 seconds).

To answer your question though, I didn't notice any difference in GPS lock time between 6.0 and 6.1.
[Tilt, TyTN II, MDA Vario III General] wisniak:
Here's my experience

I use IGO8 (legal).

With the standard ATT WM6 ROM and radio, I had mediocre battery life and phone reception, but IGO worked great (both IGO 2006SE and IGO8) and had very quick GPS fixes (I had AGPS enabled and updated(.

Upon release of the ATT WM6.1 ROM, I wan't able to get IGO8 to work (it wouldn't retain the "use GPS" setting in the GPS setup screen.

So after many hours of flashing and trials, I reverted to the standard WM6 ROM.

A couple of days ago I tried out several of NATF's ATT ROMs, with the EMO radio which has great reviews).

This radio gave me excellent battery life (at least twice the standard ATT radios), but when I changed (using Kaisertweak or Advanced Config) the USE AGPS setting, I again lost the ability to use IGO.

When I disabled AGPS - again IGO8 worked fine.

But the only issue I had with this radio was the extremely log GPS fixes (both cold and hot).

After reading several posts regarding the linkage of GPS reception quality and the radio used, I flashed the latest Niki radio, but the same issues with AGPS and IGO8 persisted.

And after over 10 minutes from cold start, I wasn't able to get a fix.

So what I did was to install the "SH4Y's QuickGPS Fix.CAB" found elswhere in XDA, and then I got a fix within 10 seconds.

I obtained hot fixes within seonds afterwards.

Now I don't have a clue regarding what exactly this CAB does (I assume some registry settings), and am not certain regarding the longetivity of this solution.

I'll check this again tomorrow, after about 24 hours have expired.

Hard SPL 3.56 fixed it for me

I'm running Dutty's Diamond V1 ROM with the provided 1.65.15.25 radio on my UK T-mobile Kaiser.

Tried Quick GPS regional registry hacks etc, but simply flashing to Hard SPL 3.56 as others have suggested is what fixed the GPS for me!

Lock in GPS Test from cold is under a minute. From warm it's ... well, very quick indeed.

This compares rather nicely with never getting a fix at all before ;)

I am a newbie, and here is the problem I am facing.

I have a brand new AT&T TILT stock ROM 3.57.502.2 Radio 1.65.21.18 (of course it's running WM6.1). I downloaded Google maps for mobile and I could not get it to work even after selecting "USE GPS" from its menu.

I am sure this must have been discussed already, but is there something I need to do to get this GPS rolling? I have heard about Telenav, is this something that's not available in this version of windows? Any quick help or even a link would be helpful. thanks.
[Tilt, TyTN II, MDA Vario III General] djcasual:
QuickGPS is broken (maybe)

After some time and headaches. I've come to the conclusion that most (maybe all) QuickGPS programs are broken. My cold starts could take 4-6 minutes to start with QuickGPS (not so quick). While my Garmin Nuvi took less than a minute to lock.

From my two months of testing different ROMS, Radios and HardSPL's. This is my conclusion to getting GPS working perfectly on my ATT Tilt running Windows Mobile 6.1.

1. Make sure you are using HardSPL 3.56 which is what ATT latest release is based on. (make sure you're actually running HardSPL 3.56. Hold down the camera button and press the reset button to view the SPL screen)

2. Radios, yes they make a difference. Battery life, GPS and call quality. I've gone thru all of them, and the ones that worked best for me was v1.65.21.14, also tried 1.65.21.18 but that battery life was shorter. Again, these versions of the radio are based on ATT latest release and are only my opinion. I encourage everyone to test what best fits you.

3. Now I'm not exactly sure if certain Radios, HardSPL or the OS/Rom version require the packedEphemeris.ee file. What I finally noticed is that all QuickGPS programs place an xtra.bin file in the Windows folder instead of the packedEphemeris.ee file. This is where I finally nailed it. I copied xtra.bin as packedEphemeris.ee in the windows folder and then my GPS started working perfectly.

+ Lock time on cold starts are under 1 minute.

+ Warm starts are under 20 seconds but usually 5 seconds.

+ Google Maps, Tom Tom and other all work fast and perfectly.

So, this explains why some of you folks using "GPS Quick Position" have no problems. Quick Position creates the packedEphemeris.ee file, and not an xtra.bin file which in my opinion does absolutely nothing. Unless someone can prove me wrong. I'll refuse to use any Quick program that places xtra.bin files instead of the packedEphemeris.ee file.

Someone needs to fix QuickGPS or start using GPS Quick Position.

Hope this helps folks. Good luck.

Thanks,

Hi,

This seems very informative, and I'd like to try it out on my Tilt.

I've tested many radios SPLs and ROMs over the past few months, and also have reached the conclusion that there's some "magic" combination between them that gives better phone/gps/battery performance.

You can see the best combinations for me in my sig.

My questions are as follows:

1. What is this "GPS Quick Position"? Is this an app?

2. How can I change the file extension of the xtra.bin file to "ee"? If I rename the file to packedEphemeris.ee, the extension remains "bin" (sorry for the noob question, it's early morning here... ;-) )

3. Your solutions requires manual intervention. This means that every time an HR is required, we'll need to follow the same procedure, right?

Thanks.

[Edit]

I forgot to mention that I use IGO8 on my Tilt, and since I upgraded to WM6.1 (either stock AT&T ROM or cooked ROMs) - I haven't been able to make it work with AGPS turned ON (there's a certain checkbox in the GPS setup screen that can't be used if AGPS is turned ON).

I've searched all over, and it's obvious this is a common problem, and certainly not radio/SPL/ROM dependant.

This means that I have to use either KaiserTweak or Schaps Advanced Config to turn AGP off, and only then can IGO8 work (acquire satellites at all).

So my additional question is, which SatNav app are you using? Have you encountered this problem?

Thanks again.

[Edit2]

OK, I copied the packedEphemeris.ee from here: http://www.htcusainc.com/clm/packedEphemeris.ee.

But AFAIK this is only a shell file, and its contents need to be frequently updated, right?
[Tilt, TyTN II, MDA Vario III General] djcasual:
Yes, a very similiar app to QuickGPS. It downloads the packedEphemeris.ee file instead of the xtra.bin file to your /windows/ directory. The sources of these files are different.

http://xdaforums.com/showthread.php?t=336599

Use a more advanced file explorer such as Total Commander. Will allow you to change file extension, copy, move and more.

http://www.ghisler.com/

However, if you decide to use Quick Position. Then this step won't be required.

Yes, if you continue to use QuickGPS (the version that saves xtra.bin files). You'll need to copy the xtra.bin file as packedEphemeris.ee everytime you download a new copy of xtra.bin. This is why I'm now using the Quick Position application instead.

AGPS is completely different from what we've previously discussed (QuickGPS, Quick Position and packedEphemeris.ee file). I've attempted to try AGPS, but from my understanding your Cell phone provider must have an AGPS server (IP:Port) to use it correctly. I use T-Mobile(US) and never found any information regarding an AGPS server. I've read other providers do have servers like AT&T. Read the following link on AGPS, and if you need help setting up the registry settings for IP:Port and Data connection. Let me know.

http://xdaforums.com/showpost.php?p=1748103&postcount=17

Correct, again this is why I'm using Quick Position instead of QuickGPS app.

Hope this helps. Thanks,

The QGPS link you pointed to is the SeaSgee GPS util. I've seen it before in XDA, did not help at all.

On the other hand, I also downloaded the avaricum.net qgps util, and yesterday I got a fix within seconds. Today I tried it twice, but this time the fix took about 1 minute.

Also, for some reason or other, sometimes I'm able to download the updated file using GPRS, other times I get an error. And as fas as I've noticed, there's no problem downloading the update file via ActiveSync.
[Tilt, TyTN II, MDA Vario III General] djcasual:
From what I remember reading somewhere (don't quote me). Is that ATT and HTC created the HardSPL 3.56 to fix GPS issues on Windows 6.1. You may want to try updating your HardSPL; even if the chef recommends you using a different SPL (such was the case with mine). It really does help, and make a difference.

Good luck,
