Problems with new IGO 8.31

I have one big problem. I am using Polaris/HTC Touch Cruise with latest WM 6.1 offical release. I have installed IGO 8.31. I have constantly GPS signal losing. GPS signal (all satelites)just disappear and then is back. About 30 sec I have GPS signal and then is about 30 sec.with no GPS signal. Basicly this software works just fine on my Polaris, but I can't use software because of this GPS signal disappearing problem.
Google maps works just fine, with no GPS signal dissapearing problem. I have 3-7 satelites all the time.
So I think that there is not problem with my device. I think that there is some problem with com ports.
Can somebody please help me
Thanks in advance.

Maybe a radio problem with your ROM. There is a newer ons... its in M'amine ROM post..: 1.59.42.23

Hard Reset
Some time (most of the times ) you need to consider one of the options:
1. Hard reset and before reconfigure your device - see if the IGO works fine
2. change ROM - since different ROM behave differently regurding your device
3. upgrade to IGO 8.0.4 - since 8.0.3 is known as problematic since 6.1

He means iGo 8.3, not 8.0.3 There is such a release but IT'S ONLY FOR PNA. Some ppl got it working on PDA, but well....many things don't work as expected. Animated menus crash the program etc. So go back to 8.0.4 and forget about those 07.08 maps for some weeks

Maybe upgrading the radio ROM might help...

forget the version 8.31
use the 8.0.0.54000
this works
the new version hav a lot of bugs and can't use the generic skins, maps, ....
there are more bugs as the version 8.0.0.54000
you ca trust me
(i test the new version for 2 days .....)

Bullsjit! The 8.3.xxxx version is way better then the previous one. I suggest u do a hard reset, install iGO8.3 and see if it works...
Upgrade your radio to version 1.59.42.23. Here: http://forum.xda-developers.com/showthread.php?t=379599 I use Khanx 1.4 with igo8.3xxx and TT7 and it works perfectly.
Maps is no problem: just follow this link: http://http://volny.cz/sstopar/mio_mapy_igo8.html and download the 2008.07 maps. They only works with Igo8.3xxx
For plugins en speedcams check this site:
http://http://www.i-go8.com/
Hope it works; otherwise PM me for some additional "questions".

Thanks guys for all answers.
I tested almost all 6.1 ROMs and both radios.
The problem is same with all ROMs an radios.
I prefer 8.31, because of Slovenia 08.07 map. This map have 72% coverage for Slovenia. Is almost perfect and works just with 8.31 version of IGO.
All earlier maps have about 40% coverage.
And I really have no more ideas why is this GPS problem.
And yes, 8.31 version is best till now. This version have some "reality view".
Someone told me that I must completely dissable A-GPS function, but in registry I can see that A-GPS is set to 0. So I think that already is dissabled.

I am using iGo 8.3.1 (sep25) with new maps and don't have any problems, working perfectly fine. Better than version 8.0.0.54000, which used to crash a lot and never worked. Using udK's R0 and radio that came with that.

Hi, everyone, I'm using the latest touch navia 1.4 pro and the iGO 8.3.1, the program seems to install fine, but hangs on for forever every time I try to run it. The radio is 1.59.42.23 and the only thing that comes to my mind is that i've put some of the content from (neither maps nor poi's) the previous version into this one, can anyone suggest something else to get it working?

Try a clean install. iGo 8.3 works perfectly for me with KhanX 1.4 Navia ROM.

Alright, worked as a clean install (with a file downloaded from a different source) after a hard reset. This was a really clean install - all the additional files (maps, buildings, etc) were added later, and it works. Thanks for advice

Sorry, don't work with clean install and Knax 1.4 ROM.
How can I completely dissable A-GPS?
Thanks

Hi guys.
I found solution for my problem.
Seems that this version of Igo don't keep GPS signal active (problem with internal GPS). You must run some another application in background, google maps,holdux,... to keep GPS signal active all the time.
But the easiest way is this:

Strange.. i dont have this problem...

I also have IGO 8.31 and I confirm that it works fine on my Polaris.... there is indeed a number of bugs but compared to 8.0 it's better.

i was testing igo 8.3.1 and i have to admit, that maps are impressive
i had no any problems with software stability, connection loosing or so
only thing i had to change was keeping tc alive - change setting responsible for power management in igo (default was stupid...)
unfortunately gps was inaccurate and had huge delay - sa there was no point to use it at all for example even with "high accuracy" my position on map ware jumping around my real location for few hundred meters (with or without "keep on road" setting active) and, on the move, igo was showing were i was about 15 sec ago (kinda off...)
definitely that's not stable version for pda
strongly unrecommend

well - some guys thinking to knowing it better ...
of course , there are some good features .. but more new bugs .... and forgotten fixing of old bugs ... ;-(

I used iGO 8.3.1 series for a week but just had to revert back to the older versions. On the whole it worked OK, no bugs, and I love the way it would display the large road signs when passing junctions on major roads, but, it was the routing, it was completely bizarre. Everything was set-up as with earlier versions but it used to take me, or try to take me completely different ways, and not even by a little, I mean major diversions within my town where I've lived all my life, and thus its usage became unbearable.
Hopefully this was just a 'one-off' so I'll give later versions a try when released.

TomTom 7 now compatible with Touch HD

A UK company are now selling TomTom 7 software that is compatible with Touch HD.
http://www.handtec.co.uk/product.php/539/tomtom-navigator-7-software---map-of-western-europe
I wonder if this will solve the GPS dropout problems that I'm experiencing with my current version 7.915. The problem is that you have to buy a new map to get the latest software, I've already paid for the Europe map, so I looks like I'll have to buy the UK map and not use it to get the latest "compatible" software and knowing my luck it won't fix the dropouts anyway .

GPS Dropout
im using TomTom 7 and Igo8 on my HD and i dont have any GPS dropout, granted when it first aquires the lock it does flash locked/unlocked for about 10 - 15 seconds then thats it, its locked and stays locked, works best on igo8 though locks straight away and stays locked, and if im honest i think i prefer IGO8 even though i have graduated with tomtom 5,6, and now 7, but still nice to have both

Unfortunately, I'm having real trouble.

Mine is driving me around the bend.
Using TomTom 7, it works fine for a time and then the GPS stops working. Exiting and restarting TomTom always brings it back. Time scale is random, it can work for hours before going tits up.
I've tried three different Roms, five different radios, two different versions of TomTom 7, AGPS is disabled, GPS mode set to 1.
It's starting to look like a hardware problem.

I've just disabled Quick GPS and deleted xtra.bin from the windows directory in case it's a corrupt ephemeris problem, I don't hold out too much hope though.

I wish mine was and it's not for want of trying.
My last hope is that it's something to do with me being, currently, in the South of France. The problem got progressively worse as I drove south from UK. Perhaps it's something to do with the phone downloading a UK ephemeris which is no good in Southern Europe. Although it must be said that I did not have this problem with TomTom 6 on my previous two phones, Artemis and TyTnII.

I've had problems with tomtom on cooked roms, but having gone back to the last UK stock rom and tomtom 7.915 i have had no problems at all.

Try to hardreset and reinstall tomtom. it´s running in generell and even with cooked roms (at least the well known wm6.1 roms i have tested)

Thanks, but I've tried hard resets and reinstallation of tomtom to no avail.
Roms I've tried are:
1.14.405.3
1.56.405.1
1.57.831.1
Dutty's 3.2XT
Dutty's 3.3XT
All exhibit the same problem with tomtom, ie random GPS dropouts. I think the only thing I can do is to buy the official release version that states compatibility, then I can get some tech support from tomtom and HTC.

The last standard UK rom from HTC is a 1.56 variant (you can download it from the HTC website with your HD serial number).
I had problems with tomtom when running versions 3 and 3.3 of dutty's roms, when either the program wouldn't start (it would just crash back to the today screen) or no satellites would be seen or the program would just freeze when navigating (used to happen a lot on 90 degree bends for some reason.
I suspect the cooked rom issues may be linked to memory usage, but i'm not sure.
I use tomtom a great deal (probably 20+ hours a week), so decided to go back to the stock rom and i've not had 1 single problem in the 2 weeks since.
You've probably covered this elsewhere in your thread, but it may be worth installing HDTweak and making sure that you've got AGPS switched off.
Good luck
Spudgun

anyone know what the version is ?? 7.x or 8 ?? that's offically supported

As there isn't a navigator 8 yet, I would be absolutely shocked if it was anything but 7.x

I'm using the same rom as you at the moment with no luck. Tried all permutations of agps/no agps using hdtweak and gps mode in registry, also tried another SD card. This is so annoying as I'm on a driving holiday in Europe. I've just downloaded Davideuck's WM6.5 rom and will try that, clutching at straws here.
The freezing you had with Dutty's roms sounds like the same problem I'm getting. It's completely random, can work fine for hours and can freeze twice in five minutes, mine seems worse in slow or stationary traffic, but it can happen anywhere and usually does it at the most inconvenient moment. If I exit and restart tomtom, it comes straight back. I suspect it's something to do with timing somewhere.

Which version of the maps are you using?
Where have you got tomtom installed (i've got it installed on the device)?
Which radio are you using? (i've found 1.13 to be the most reliable)

Device

WM6.5 rom now installed and running, just going for a drive to try it out. Not holding my breath though.

best of luck to you
Do you do a 'clear storage' when you flash? just in case there is a bad settings file somewhere on your storage card?
I had a torrid time getting tomtom to work 100% reliably on a cooked rom, but have never had any problems on a stock rom, so this has effectively cured my 'flashing fever' and i'm happy to stick with what i've got now, especially as i had tomtom lockups all the time on a way to a wedding in central manchester a few weeks back that caused no end of grief in the car

Arrrrrgggghhhhhh......
It did it again .
The only difference this time was that the navigator screen went grey and showed no satellites rather than pretend that nothing had happened and carry on showing motion albeit slowly leaving the road. It looks like it's the gps module switching itself off from time to time and requiring a restart. I seem to remember seeing something about a registry controlled timer, I'll look into that now.

What you describe above is exactly what happened to me when i was running one of dutty's roms. I would lose signal and it would wander off road before going round in a big circle and ending up at the point where it lost signal. I would also find that for some time afterwards i was unable to see any satellites in any GPS application.
I tried flagging it up on the forums here thinking it was an issue in the cooked rom, but I didn't get anywhere. Thankfully a stock HTC rom got everything as it should be and i navigated without any issue at all around the south east of england for 3 days (approx 18 hours of GPS time) last week and also made a couple of trips this weekend without issue.

Back to topic:
http://www.handtec.co.uk/product.php/539/tomtom-navigator-7-software---map-of-western-europe
So is this a legit TomTom Navigator 7 package for HTC Touch HD?
If so, great.
But I also need North America maps. Where would I be able to purchase those from, or would I need to buy them in the US? Is it then just as simple as loading the new maps onto a card?

GPS - no fix

Hi, I got my Topaz today and im very dissapointed, I have no gps fix in any navigation software even in google maps, its still seeking for gps satellites (0) but no progress. Did anyone see this problem before, any solution or I've got damaged device and I must send it back?
// ok now, i got already fix fine but it takes couple of hours to get it, interesting.

a clouple of hours for a fix? that doesn't sound right, have you updated quick gps?

I followed the advice here:
http://blog.mohdimran.com/htc-touch-pro-gps-problem-tweaking/
and haven't had problems since. Even after an extended period of non use I get a fix after 1-2 minutes.

Use:
Com-port=4
Baudrate=57600

Are you inside a building or utside ?

Also if you have installed the VOIP cab file then your GPS will not work and you need to follow this post to rename a file and then restart your phone. After i did this my GPS worked very well and I get a fix within 20-30 seconds!
http://forum.xda-developers.com/showthread.php?t=402228&page=8

With Com-port 4 and Baudrate 57600 i have when i ma outside a fix within 5 seconds!!
When i walk inside my house iGO8 will keep a GPS fix.
I must say that i own a old house from 1923 with no concrete and rebar so that helps with a GPS fix inside!

how can i set the baudrate when i using the internal gps?

For iGO8 goto: Settings 2/2 and click on GPS, there you can set comport to 4 and baudrate to 57600.
For TomTomNavigator goto Preferences 6 of 6 and click on Configure GPS, then again click on Configure and select: Other NMEA GPS reciever then you can slide the baudrate up to 57600 and after that select com4.
For other navigations i don't know where to set it.

I've done some testing and it looks works properly, when im tryied thirst-fix it was a little rainy day and I've hold a device in a hand and that was the problem i think. Device can't be in movement when I put it on the desk outside of house it allready fix the position ( it takes some time ). So im happy now, good-end story : ) Thx all to yours advices and sorry for my bad english, I'll hope you get the point xD

I notice the same experience:
- It's difficullt to get fix if you hold the phone or when moving
- It will fix easily and take not long for first fix when you put it outdour e.g on top of a car
- Fix time is unstable, sometimes it gets fix in 20-30 seconds but other time it takes long time, even can not fix
Compared to other GPS phone like Nokia 5800, the Topaz GPS reception is very bad.
(PS: I have tried a lots of GPS tweaks, tips but did not help much)

I am using newest Radio - 4.47.25.21 and ofcourse QuickGPS is a prerequisite...I get a fix in 10-20 seconds irrespective if I am standing or moving. Country - Singapore

i must agree, since upgrading to the 4.47.25.21 radio my GPS reception has been superb. I generally get a fix in under 30sec.
Even had a fix in my house after installing tomtom to set the preferances, was quite supprised that the GPS was getting signal, something that never happens in my house with any previous device or other radios.
Think if the battery drain is not high this radio will be a keeper

touch hd gps

Hi
i have read in a few other posts regarding GPS issues and Sat Nav software not working
now i have seen a few programs that 'kick off' the GPS and then runs the program and i have run these to no avail,
i was wondering if anyone else has not only had this issue but struggled to get it working, google maps seems to pick me up via GPS but tomtom is saying 'no gps device' go into settings within tomtom and set to internal gps device, and check gps status and no cannot see any satellites. i have had the phone outside inthe line of sight of the sky for an hour so me being inpatient isn't the issue, any help would be greatly appreciated
ta

Try this:
http://handheld.softpedia.com/get/GPS/GPS-Test-34335.shtml
Update QuickGPS.
If no satellites show up after a max of 5mins of you standing outside with clear view of the sky, then you either need to flash another radio or the gps is dead.

hi
thanks
have left phone outside running that, seems to be scanning com1-9..pausing for a second on port 3 then continuing. will let you know in 10 mins, what is flashing another radio involve?

ok stupid question time, but if it google maps seems to be working ok would that not suggest that the GPS radio is ok, and secondly if i did flash which one would i go for on that link you sent

am i flashing this even though my protocol is different?
and there is about another 10 files below all them called

all confusing can you help any more please
thanks

I don't believe anything google maps says in relation to GPS after it told me one of my non GPS phones had inbuilt gps, and then calculated my position using the mobile phone network.
As for which you need, well it depends on which rom you are running, whether it's a stock rom (bog-standard rom you get on device when you buy it), or a custom cooked rom from someone on the forums. I suggest you read up on it thoroughly then post in the correct radio thread if you want to ask any more questions regarding the right radio version you need.

fair do's
thanks

Did you have google maps open when you started Tomtom? That may have caused an error

hi
thanks for reply, no i open google maps it seems to find my location. close google maps, then open tomtom and is saying no gps device. the 'onboard' gps device is set on tomtom options it's just as if the gps reciever isn't picking up, same in other sat nav progams too, garmin is the same so makes me think is phone not software issue

AFAIK, Google Maps is A-GPS software, while TomTom, iGO and others are full GPS software.
Don't know about TomTom, but iGO DOES NOT work if A-GPS is enabled...

hmmmm. i'll give it a whirl, not got the phone withme at the mo, a mate is attempting to simunock it, agps is enabled so i will disable it see if that helps. tempted to get rid and get an effing iphone at this rate

Let us know how you go....
Don't give up, it;s a great phone

had the same issue with tomtom v7.450. using tomtom v7.916 now and it's running like charm

Just had replacement Touch HD delivered from Orange this morning, flashed to my usual ROM, and get exactly the same symptoms as Pete did.....
Tried:
TomTom
Memory map
HTC GPS Tool
Updating QuickGPS
Updating Radio ROM to latest version
Reflashing different OS roms
nothing makes a difference.
Not really keen to take it apart as i'll break the VOID sticker and probably end up in an argument with Orange, but Id bet any money that the GPS cable has come loose......so frustrating as im working abroad as of next week and i'll really use the GPS a lot......
Also just found out that the replacement handset is "refurb".....I bet the muppet that refurbed it didnt reconnect the GPS cable

GPS Not working?

I have tried villian rom and modaco rom but when i enable gps sattelites in the phone option it says its enabled but gps applications never get a fix and the satellie symbol doesnt ever appear in the task bar. Also I dont know for sure when this started happening because i have not tried using gps for a while, but would flashing the hacked spl cause it? are there any fixes?

I have tried Villian 5.2 and aHero 0.7, with Radio 63.18.55.06JU_6.35.09.26.
GPS get a lock, short time later it lose the lock.
Tested with different Software (GPS Test, Igo, Navigon, Maps)

I have tried Villian 5.2 and aHero 0.7, with Radio 63.18.55.06JU_6.35.09.26.
GPS get a lock, short time later it lose the lock.
Tested with different Software (GPS Test, Igo, Navigon, Maps)

I noticed following with my phone: GPS gets lock (with Navigon, Google Maps ...) and works fine while phone is connected to the 2G base station. As soon it's switched to the 3G, GPS losts it's lock. If 3G is disabled (*#*#INFO*#*#) everthing works fine. Also lock gets back as soon as 3G is disabled. I'm using MoDaCo 3.2 and did try two different radio ROMs: 63.18.55.06JU_6.35.09.26 and 63.18.55.06JU_6.35.08.26. Hope this helps.

on the 2.1 roms that are available atm the phone needs to be booted with gps turned ON, otherwise it won't find a fix. when you are going back from 2.1 to 1.5 (e.g. modaco) you need to reflash the radio to make the gps work again. that is valid for the JU 09.26 radio, not sure about older versions.

There was an issue with flashing some of the 2.1's and then going back to a restored ROM. I am using the Mr Bang Performance rom, but couldn't get a lock. The solution was to reflash the radio and it should work then.
I'd give that a go, it might sort you out.
EDIT: I see kerndog already pointed that out...

ah perfect, reflashing the radio worked! thanks guys
