I'll put both hands up to that! There's clearly an issue with it but when I called HTC to ask them to fix it I got the old 'we've not heard of that before' line and that they'd have to try and recreate the problem on a TyTN II they have hanging around there. Perhaps if they get masses of calls all saying the same thing they may believe me and start to do something about fixing it.

Since they don't seem to be very good at matching hardware to windows mobile via drivers (where they've actually bothered to include drivers that use appropriate hardware that is), my strong suspicion is thats the area that needs attention. If Quick GPS was the culprit then restarts in the same general area after a Quick GPS update should be fast but unless the TyTN II remains in exactly the same place it's not - it's significantly slower than under WM 6.0.

I've also reported it to Tomtom but they've said they need to work with HTC on a solution. My suggestion is to report this bug to both HTC and Tomtom as many hands make light work. Has anyone got a 'yes we're aware of that issue and are working on fixing it' type response yet or are they still claiming not to have found a problem? Don't bother trying anything other than the inbuilt gps receiver under Tomtoms configuration - it make no difference.
[Tilt, TyTN II, MDA Vario III General] Karolis:
I couldn't wait till tomorrow, so I did a hard reset on my device, installed TomTom right away, downloaded QuickGPS data and ... got a lock in under 2 minutes! Not bad for a cold start.

Say whatever you want but there's no way I'm touching that External GPS setting again.
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
There are situations where I can get a lock in under 2 mins with my new HTC approved WM 6.1 ROM but they're few and far between. Further more in those same situations under WM 6.0 it would have taken under 1 min and the reception bars would have been far more stable. I'm pretty sure it's a good old driver issue - I'm going on HTCs past track record as well :D
[Tilt, TyTN II, MDA Vario III General] Karolis:
Well, unless someone from HTC has read this thread and sent some satelites over my house, I simply cannot confirm this problem.

Since I have done a hard reset and installed TomTom, GPSTest, and HTC GPS Tool, I had no problem getting a lock. Multiple tests in a row (using all three of the mentioned apps) got a lock in under 20 seconds.

I will try to see what the results are in different parts of town tomorrow and then let you know.
[Tilt, TyTN II, MDA Vario III General] rikbrouwer:
Hey, I think setting the GPS in TomTom to 'other NMEA' with settings COM4 and baudrate 19200, actually worked. Got a Cold Start fix in less than 30 seconds, just like old times! And this was even inside my house.. thanks!

I'm also using the Official 6.1 ROM (dutch)
[Tilt, TyTN II, MDA Vario III General] Boinng:
The "external GPS" applet certainly can cause problems, but that's not the answer for me (or I suspect plenty of others) since the issue has persisted for me through various hard resets, while I've studiously avoided touching those settings or even opening that applet.

It may be that this is an issue with the internal GPS driver, and setting Tom Tom manually to other com ports etc can get around that (although I don't notice much improvement) but that's not possible in all GPS software anyway, so I don't think it's much of a solution.

The real issue is the lack of assistance from Quick GPS - which doesn't necessarily mean a problem with Quick GPS itself of course - without it you can still get a fix, and sometimes you may even get a fast fix, but it's the lack of a consistently fast fix that's the major problem.

Fingers crossed for a proper fix from HTC.
[Tilt, TyTN II, MDA Vario III General] rikbrouwer:
Ok, have to change my previously stated opinion regarding the change of baudrate. It shows definitely some improvement, but indeed: sometimes in open air it still takes up to 2 or even 5 minutes to get a fix from cold. This never happened on the stock WM6.0 ROM, so it must be something else.

QuickGPS not working properly sounds more plausible at the moment.
[Tilt, TyTN II, MDA Vario III General] Karolis:
I have to change my previously stated optinion too. I have done some testing in the city today and the results were very poor. First time I got the lock in only over two minutes while second time I have walked all the way back home (~15 min. walk) till I have finally got the lock.

I think HTC has sent some more satelites over my house afterall :D

P.S. It seems that running GPS Test, getting a lock and then running TomTom speeds thing up a little.
[Tilt, TyTN II, MDA Vario III General] splbound:
I have the exact same problem.

GPS locks were quick using the standard WM6 Tmobile UK rom and 1.27.12 radio

Currently using:

Dutty's april 29 6.1 rom

1.64.08.21 Radio

GPS locks take much much longer than with 6.0 (consistently under a minute).

I have tried changing radios, hard resets etc.

No errors running quick GPS.

Servers in registry pointing to: xtra1.gpsonextra.net

Region set to UK

What I notice it that when running gpstest 1.04 and GPS stating up is going. I initially don't get any satellites showing up. If the quickgps data is properly downloaded aren't I meant to be able to see the satellites show up?

Other than this problem with crappy gps lock times the ROM is excellent.

Anyone have any more insight to this problem? I think I'm going crazy.
[Tilt, TyTN II, MDA Vario III General] splbound:
Alright .. after reading some more posts I read that although quickgps is downloading the data correctly the radio was not using the data.

See the-uki's post on:

http://xdaforums.com/showthread.php?t=388947&page=115

Sounded very plausible to me as gps test was not reporting any satellite positions when it started up.

If it was using the quickgps data properly the satellite positions quickgps loaded should have shown up with 0 signal.

Updated the radio to the Nikki 1.58.11.07 radio as one user suggested (Only tried the Kaiser ones before) .

Now the quickgps satellites are showing and am getting lock times in line to when I was using the WM6.0 and 1.27.12 radios.

I am currently testing this setup at the moment to see if this change killed anything else I was happy with.

Hope this helps with the investigation.

Update:

After the first day of testing everything looks good, the rest of the phone are working as normal. Experiencing extremely quick lock times possibly even faster than when using the 6.0 rom and 1.27.12 radios. I am one happy camper now.

In retrospect the gps cold lock times for me were really bad using the 1.64.08.21 radio. There were times when I had 4+ greens bars using gps test and the thing still was not locking after 5 - 10 minutes. The problem for me definitely looks like the radio.

Thank you to the people on this forum for providing the tools to make the device GPS usable again.
[Tilt, TyTN II, MDA Vario III General] Karolis:
You were probably refering to this post: http://xdaforums.com/showpost.php?p=2169539&postcount=1144

I will try the workaround too. But then again, this is what it is – a WORKAROUND rather than the sollution. If someone wanted to stay "legit" (no flashing, etc.) they could not really fix the problem.

UPDATE: I confirm that using NIKI radio with WM 6.1 fixes the problem – after downloading QuickGPS data, satelites appear even if there's no signal yet. I've done some testing around town and I didn't have to wait longer than 1 minute to get a fix. Fanstastic!

I think HTC should release a radio downgrade utility – that would be a fairly simple fix for everyone willing to keep stock software.
[Tilt, TyTN II, MDA Vario III General] gai-jin:
I installed this radio today, along with hardspl 3.29, and now my camera doesn't work. Have any of you tried the camera since downgrading the radio?
[Tilt, TyTN II, MDA Vario III General] Karolis:
Shoot, I didn't check out the camera - indded it doesn't work :( I'll look for a fix and let you know if I find anything.
[Tilt, TyTN II, MDA Vario III General] mrschwarz:
I upgraded to Dutty's latest and had gthe same GPS problem. I reverted back to his 4/29 version and the GPS problem remained. I have tried other radios.

I tried 1.58.11.07 and it really hasn't helped. My camera still works, though. Still looking for GPS solution.
[Tilt, TyTN II, MDA Vario III General] Karolis:
Well, if I had to choose between camera and GPS, I'd go for GPS, but hey, I've paid ****loads of money for this thing, I don't want to compromise.
[Tilt, TyTN II, MDA Vario III General] gai-jin:
On top of that, once I try the camera and fail, audio seems to stop working until I soft reset.
[Tilt, TyTN II, MDA Vario III General] splbound:
The camera works fine with me. Though I am using Dutty's rom and not the official 6.1WM. I have also recently hardspl'd it to 3.29.

My Current working spec is:

Rom: Dutty's april 29 6.1 rom

Radio: Nikki 1.58.11.07

SPL: HardSPL 3.29

My phone was bought through T-Mobile UK as an MDA III.
[Tilt, TyTN II, MDA Vario III General] pjam:
Just tried that latest mentioned radio and seemingly no change on the GPS side of things. My camera would launch but was a blank screen.

I'm using Dutty's latest V1 diamond rom with Hard SPL 3.29

I have been recently... only realised it today...
[Tilt, TyTN II, MDA Vario III General] gauntman:
I´m using the stock 6.1 ROM (Swedish) and it came with stock 3.29 spl. I´ve got good GPS performance. Cold start with clear view of the sky is about 20-25 sec. I´ve also noticed that it will get a fix faster if I get moving while trying to get a fix, standing still will increase time with about 10 sec. This is with quickGPS updated, never tried it without. I´ve also disabled AssistedGPS with Kaisertweak because IGO didn´t work with it enabled and that somehow got the GPS to fix faster. Indoors with almost no view of the sky I get a fix within a minute. The radioversion for my ROM is 1.65.16.25
[Tilt, TyTN II, MDA Vario III General] tilted 9825:
it works for a novice user like me

works great for me,

just had to do a little work as this was my first time with a windows mobile device

thanks a lot
[Tilt, TyTN II, MDA Vario III General] Draqula:
I have TyTN II with official WM6.1 upgrade from HTC.

After the update, as many of you, can't get a fix in acceptable time.

HTC GPS tool shows 2 satellites a red, right in the start, their levels change and in time it even shows up to four satellites, but still no fix (waited for 5minutes, then gave up). "Satellites used" was 0 all the time.

So I've been seriously looking at the new iPhone - 3G, GPS and Exchange support is all there and updates for previous i-products have been regular.
[Tilt, TyTN II, MDA Vario III General] jeffla:
Before figuring this out it could take 1 min to 10 mins to get a lock with pretty much any radio I tried. I gave up on Quickgps a long time ago. Just too unreliable, some days it populated Tomtom other days it didn't.

Run gpstest, it normally takes 30 secs to get a good signal

Select Menu and then Minimize

Now open TomTom

I get a gps signal fix almost immediately after it initializes the gps unit.

Jeff
[Tilt, TyTN II, MDA Vario III General] pjam:
I have just gone back to using the official HTC 6.0 release with the original Hard SPL 1.0.

The GPS fix is certainly much faster than the couple of 6.1 roms i have tried.

Think i'll stick with this for now. (Love my GPS)

pjam
[Tilt, TyTN II, MDA Vario III General] Esteel:
I am running the HTC 6.1 Official ROM. At first I had unreliable GPS performance. I upgraded the radio to 1.65.20.29 and now my GPS performance is really improved. Twice I've gotten satellite lock inside my house.

Eric
[Tilt, TyTN II, MDA Vario III General] ardsar:
I doubt that the issue is fixed- ie by changing the radio you are still NOT using the quick gps data. I suspect that whilst connected to the satelites with a signal lock, you have probably downloaded enough of the almanac data (data that contains the locations of all satelites at a given time) from the satalite to enable you to get a fairly fast start. If you don't use your gps for a week, i suspect you will have a long startup time again which you would not get if the quickgps data was being used.

I
[Tilt, TyTN II, MDA Vario III General] motocrossmann:
Thanks!

Wow, that worked great! I was struggling with 5-10 minute satelite fixes, and after updating to 1.58.11.07 and HardSPL 3.56 (not sure that did anything), I can locate in 10-30 seconds, even on a cold start. I'm using Duttys Hybrid v2, btw...

Thanks guys!
[Tilt, TyTN II, MDA Vario III General] dengi_it:
Wow, I just tryed once and it immediately worked pretty fine!

I'm using the standard HTC 6.1 version and had many toubles with GPS. Using QuickGPS sometimes it worked, sometimes not.

Now I donwloaded Gpstest and tryed from my office (so inside the building, close to the window) and it immediately worked! As adviced I launched Gpstest and then minimized it. After I lanched my navigation program (Wayfinder) and it immediately got the signal!!!

I will do other tests but it sounded a great advice

Thanks Jeff!
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
What if the problem is the radio (which acts as the GPS driver) as I believe the case is? Surely the ultimate test is whether the fixes are quick and reception is stable - something I'm not getting with the HTC WM 6.1 release. I can't see how it can be QuickGPS causing the problem because no matter what situation you attempt to get a fix under and how soon after the last fix it's obtained, it's still much slower than WM 6 in the same situations and signal reception is still less stable and strong in the same situations. It has driver issue written all over it and HTC are up to their old tricks as far as accepting there even is a problem so far.

My question for Esteel is have you tested the other functions the radio module deals with such as the camera, sound and even graphics (to an extent)? I read elsewhere of someone who fixed the GPS problem with a radio upgrade but then got a black screen with the camera.
[Tilt, TyTN II, MDA Vario III General] sebbes:
For what it's worth.... I tried the other way around :

With the Apr 29 Dutty's WM6.1 + Radio 1.65.14.06 + QuickGPS : bad GPS lock...

So I went back to my French Orange WM6.0 (leaving the Radio) : very quick GPS fix

Anyone has a link to a cab for installing Orange's AGPS (called GPS+) ?

I definitely think it's a problem between QuickGPS and the radio stack.
[Tilt, TyTN II, MDA Vario III General] ardsar:
If quickfix gps data was being used, it would not take 10mins to get a sat lock, even from a cold start or sat in doors (locations where it worked with wm6). The signal strength i receive is adequate and once locked, i can maintain this lock in doors as good a with wm6. The signal strength is approx the same level a before.

Many ROMS based around wm6.1 have this problem and agree with the above that the problem lies with the implementation of quickgps, wm6.1 and the radio somewhere ...

Suggest we all get onto htc.
[Tilt, TyTN II, MDA Vario III General] Karolis:
So it's been quite a while since the new ROMs & Radios came out, and there's still not fix but to flash to a different Radio? Too bad :(

The one thing I can't understand most is why for some people it just works, even with the same ROM and Radio version I use.

I know that by asking this I will go off original topic again, but did anyone find a working combination of ROM + Radio? It seems that no matter what combination I try, I have to sacrifice something (GPS, camera, sound, etc.)
[Tilt, TyTN II, MDA Vario III General] moto2000:
ill just have to add that ive been doing testing on this as well.

Ive tried pretty much every radio since upgrading to WM6.1 and have concluded that it is either a problem with the new custom 6.1 roms or 6.1 in general. but all WM6.0 roms had amazing GPS locks.

After upgrading to 6.1, GPS started sucking bad.
[Tilt, TyTN II, MDA Vario III General] PerfAlbion:
I also noticed long lock times on 6.1. Yesterday, I installed the latest Garmin software update for Mobile XT and today, my lock times are back down in the 5-10 second range.

I'm wondering if the issue isn't the ROM/Radio but some crappy GPS dll that Mobile XT overwrote as a part of the update. If anyone knows the files I should be looking at for dates/times/details, let me know. I can post the version information I have.

But the difference literally is night & day. Garmin Mobile XT version number is 4.20.50wp after the update. Tried using it last Thursday and getting a lock took forever. After applying the update, no issues at all.
[Tilt, TyTN II, MDA Vario III General] Esteel:
Well I have to disagree. No matter what radio or rom combination I had tried in the past I never got a satellite lock INSIDE my house. The official HTC 6.1 ROM with HardSPL 3.29 and radio 1.65.20.29 has given ME the best performance on my GPS to date. I haven't noticed any problems with camera, other radios, bluetooth or battery.

As for battery, it's been off the charger for 15 1/2 hrs. I had 5 phone calls, about 60 e-mails, and some web surfing today and I'm currently at 62% battery. I just did a speed test and rated 1047 kbps.
[Tilt, TyTN II, MDA Vario III General] Farsquidge:
That is probably why mine seems OK too.

I only use Garmin Mobile XT and keep it updated and don't have any issues with the GPS lock from WM 6.0 to 6.1.
[Tilt, TyTN II, MDA Vario III General] ardsar:
I've contacted HTC with regards to this issue, who have now esculated it to the engineering team. Suggest others do the same for a quick solution.

Hope this helps.
[Tilt, TyTN II, MDA Vario III General] Karolis:
I have contacted them but never received any answer.

Thanks, I'll have to try the combination. Couple questions first:

1. Are you using Radio 1.65.16.25 or NEON radio? It's not quite clear in your post.

2. And also have you noticed any "side effects"?

3. Does it fix the issue of not using QuickGPS data or does is just make GPS work a little faster than other combinations?
[Tilt, TyTN II, MDA Vario III General] sebbes:
I tried couple more things by switching back (and testing in house):

- to HTC WM6.0 ROM + Radio 1.27.12.17 : less than 1mn fix

- to HTC WM6.1 ROM + Radio 1.65.16.25 : nearly 10mn, still no fix

- HTC WM6.1 ROM + Neon's radio : didnt help for me...

- HTC WM6.1 ROM + Radio 1.65.16.25 + Garmin Mobile XT : GPStest finds one, or occasionnaly two "green" satellites... but still no fix in a reasonnable delay.
[Tilt, TyTN II, MDA Vario III General] Karolis:
I'm tired ot testing multiple radios every evening. I give up.

Will wait for official fix (which might never come) or have to downgrade to WM6.0 when I have time.
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
Why should we have to try and fix things ourselves. I'm in the same situation. I don't want to be the beta tester for HTC with my very expensive phone. It'd be different if HTC provided me with it for free to do some testing but they haven't and I know they'd be very keen to void my warranty at the slightest whiff of an unauthorised ROM or Radio being flashed onto it - hence I rely on them to come up with the goods.

I encourage you to contact them again and ask them what's happened to your reply. Don't let it rest! I'll be contacting them again on Friday about it.

It must be at the point now where at least they cant say they'd not heard of this problem and claim ignorance. Has anyone heard anything promising from them yet or gone beyond level 2 tech support on the issue?
[Tilt, TyTN II, MDA Vario III General] pachjo:
I have updated with the stock wm6.1 from htc site and as yet have not found any issues with the GPS?

When I fire up TomTom on my TyTnII the signal picks up within a minute or two each time here in UK.

Although when off to Europe next month as a backup I shll be bringing my TomTom One as I do not wish to get half way cross Europe and then experience problems!!

I too share the thought that I am more likely to stick with the official ROMs as I paid £440 for my TyTnII and would cry if I bricked it!

Also it all seems too complicated in trying to apply a cooked ROM, well it is for me anyway!!
[Tilt, TyTN II, MDA Vario III General] mrschwarz:
I'm using:

Dutty's 4/29 ROM

Radio: 1.58.11.07

Hardspl 3.29

Everything seems to work. GPS lock times are extremely quick.
[Tilt, TyTN II, MDA Vario III General] vcespon:
I never had serious problems with GPS on my Kaiser, and I have flashed it like 30 times witrh different ROMs and radios

Some radios get a cold fix faster, but hot fix usually takes only a few seconds.

Best radio for GPS seems to be 1.27.12.17, followed by 1.58.26.20.

GPS fix with the new 1.65 radios has always been slower for me.

I'm running 1.58.25.17 radio now and cold fix it's about one minute, and hot-fix is 1 second.

Just to clarify test conditions:

- All tests done on a clear space, clear sky (my work place's parking lot)

- Cold fix means soft reset, open GPS program, wait for fix

- Hot fix means get a fix, stop GPS on the program, start again

GPS navigation with 1.58.26.20 or 1.58.25.17 on city (among buidings) seems better than with other radios, I do not lose the possition so often.

I have had the same issue with gps but I am also having problems connecting to my tomtom plus service account if I'm connected to the network for data says "an error occurred on your tomtom device please try again" but if I'm connected to wifi it will connect to my tomtom plus account but still no gps lock" I am on rom 3.28.405.0 wwe (official htc) on my att tilt on att network all configured correctly and radio 1.65.16.25 another strange issue I am having with this rom is I cannot receive weather information from the home screen unless im on wifi if im connected to network for data says "unable to retrieve data for selected city" anybody else having this problem that also has the gps problem might the two problems be related?

I have noticed something weird yesterday, which I can confirm today: in about 2 minutes from starting the GPS, QuickGPS data seems to kick in, because suddenly both TomTom and GPSTest start showing 9-13 satellites. However this doesn't help to get a lock any quicker. Total lock time is around 5 minutes.

wolfnumba1, I'm sorry but it seems like this is not exactly the thread to post network issues. But I hope someone can help you.
[Tilt, TyTN II, MDA Vario III General] wolfnumba1:
