TOMTOM 6 Backlight issue

Oki here we go again. I have been looking for backlight fix of TomTom 6. I did find a link from the forum ages ago but now I can't find it.
I have installed C_Shekar new 6.1 Rom and installed my TomTom on it. When running tomtom the backlight switches off and I cannot see anything on the screen. Someone pointed (ages ago) that WM5 has issues with it and he gave me the fix for it which was working fine uptill now. I have tried the fix error message cab file from the forum as well but no luck. I think I need to edit the registry file for TomTom from backlight to bbcklight or something.
Now when I run TomTom with backlight fix it gives the following error message:
==================
The file 'TomTom Navigator' cannot be opened. Either it is not signed with a trusted certificate, or one of its components cannot be found. If the problem presists, try reinstalling or restoring the file.
========================
Please help!
Regards
Jay

Oki I found another TomTom version which is working just fine.

Great news
Just a quick question... which version of Tomtom are you using that has fixed this issue? There seem to be different opinions about which one is best...
6.100
6.032
6.030
6.020
6.010
Do you ever get a "jerking" problem where the position goes forward and backward along the same road as you move (instead of moving forward smoothly?).
Thanks.

Afternoon! I am not sure what version of tomtom it is exactly as it doesn't say on the file I downloaded. All it says it is "TNT2007" and nothing else. I have tried to check its settings from within TOMTOM but I was unable to find the version number.
Yes! there is a "jerking" problem, it did it when I went to France from UK through a road trip and it was getting stuck in Paris. It didn't find the most important places like "Eiffel Tower, Champs Elyees" even though I setup POI's, tried manually entering the name and still nothing. I wonder how POI's work in this software.
anyways all things aside, if you want the file I can upload it here and you can download it and try it out?

I'm using TT too, (Version 6.200, to find out: tap screen, settings, GPS Status lower right corner) and i have the same Problem. someone who kwnows how to solve?
My workaround: press call answering, start, settings, system, Lights, battery tap twice on checkbox, close... back to TT and lights on...
It seems that TT forces the Lights-settings...

btw: sorry for my bad english, i'm german ;o)

To find your version of TomTom open the software and tap the GPS signal strength meter in the bottom right corner. Your version will be displayed in a white box in the lower right corner. I am using version 6.010 on an AT&T Tilt using the latest stock ROM minus the bloatware. I have little issue with how the screen scrolls, it is a lot better than my old iPAQ.
To be able to find POI's you need 2 things, a map, and a list of POI's. You don't always get a complete list of POI's with the map. If I was traveling out of the country I would make sure I had all the proper maps, and POI files before I left home.

I used to tap the red end key on my old iPAQ to minimize TomTom... I think the green key brought up the dialpad.

The best solution is using a hex editor to open the exe file under tomtom folder.
Search for Backlight and replace the 'a' to 'b', becomes Bbcklight.
Save and replace the original exe file.
Sounds a ridiculous way but it does work for all versions.

Suggestions
Hi Jay,
Sorry for taking so long to reply to your suggestion - work has been getting the better of me.
I've now trialled a number of different versions of tomtom and I believe the best one for this ROM is v6.032 build 8351.
Try googling "tomtom 6.032 torrent".
In terms of jerky and slow screen updates I've found a major improvement by backing up my SD card, re-formatting it (full formatting, not quick formatting) and then copying the map back first, and then everything else that was on it. It seems that my SD card was fragmented and defragging it made a massive difference. I didn't believe it would when I first read about it on another forum, but it really works!
I've also found a slight improvement by overclocking the CPU using the program XCPU Scaler v3.03. It runs tomtom at 472mhz. Not as big an improvement as the SD card trick, but still a small improvement.
I still think that tomtom performance was better under wm5 AKU2.3 (and even wm2003se) but we get quite a few more features with wm6.1.
I now have no backlight or other issues.
I hope that helps.

i have 2 phones one with wm6.1 and one with wm6.0 will tomtom woke on the 6.0 already have it on 6.1and works good

*Hopeless* GPS after 6.1 Update?

I know this has been touched on before, but I want to know if this is a widespread thing or what - since the official 6.1 update, my GPS has been really poor, particularly on a cold start. In fact, every time I use it feels like a cold start these days, even though Quick GPS is downloading data regularly and always shows 6+ days.
Every GPS app is the same - Tom Tom, GPS Test, Google Maps, Live Search - I can be waiting up to 10, 15, 20 minutes for a fix. The only time it's quicker is if I've used the GPS recently, and even that is a bit of a black art.
I like running the official ROM and I'm happy with the update in every other way, but the GPS problem is driving me up the wall - am I the only one? Is anyone running the proper ROM and not finding their GPS impaired?
The weird thing is, I can watch GPS test picking up two, three, four satellites but it just won't lock...
This is with the WWE 3.28 ROM with the 3.28 SPL loaded (fixing the freezes under Hard SPL v1)... what's going on?

Usually, I've found the GPS lock time is Radio Based. Maybe try a different Radio.

The only thing that is going to get me off the DEATH V3.5 ROM is a newer Rom by this same person.
The GPS is the best that I have ever had...
The phone signal is the best that I have ever had...
The GPS lock is about 30 seconds after TomTom starts...
The battery life is phenomenal - (it takes about 24 hours for the phone meter to register correctly) but I had 79 percent battery life left after using the phone all day yesterday at 11 pm last night (unplugged it at 6 AM).
Obviously - your carrier, your radio and ROM and where you are in the world can affect your signal greatly - but at this point - for me - the DEATH V3.5 ROM and radio rock and will stay on this phone as I LOVE having no phone issues.

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?"

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

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.

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.

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.

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.

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.

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.

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).

I was just browsing through an interesting thread here - http://forum.xda-developers.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?

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.

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?

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

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://forum.xda-developers.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.

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?

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.

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..

Diamond Gps Sucks

I am so annoyed with HTC Diamonds GPS. It just sucks and doesn't work. I had earlier updated the radio to 1.25.06 and then it didn't work. Other members over here advised to switch to 1.25.05 and yet it doesn't work. I did a hard reset too but no luck.
Map King fails to work and Google Maps keeps on saying trying to seek Satellites and yet it just shows 0.
I am truly disgusted with HTC and will never again buy their products

Funny, I have a Diamond too, and my GPS works perfectly. Actually it's the best GPS I've ever seen. Flash 1.93 ROM, then use QuickGPS to download actual GPS positions and try again.
By the way, you're not trying to run GPS inside the buildings are you? Go out into the street and try there. GPS doesn't work inside.

I had a flat tyre on my Mercedes the other day! I am so annoyed with Mercedes!
I will never buy Mercedes again!!

you need out your battery from your phone and put it back after one minute.

GPS works perfect on my Diamond. Much better than some car GPS devices i've seen. Dunno why yours doesnt work. Maybe you are a noob?
Doesnt work inside buildings btw..

Mine also working fine with MapKing2007 and HTC GPS Tool....
BTW I'm setting it at 57600.... is this fine? or actually does this setting matter?

I am currently running Swift Rom v5 and yes i am trying the Gps outside. Regarding the settings in Google Maps, i have kept it to automatic. QuickGps is also updated.
I will try the battery thing and will set it to manual
Thx to everyone for their input,

As the "I will never buy a HTC again" threads are coming up in decent sequence, I would dare to see a system behind it if I would be a bad mood. Backdoor marketing at a glance?
My TD GPS is the best I ever had. Sat fix with a loox N560 and Navigon MB6 - 2 minutes waiting. Same with my TD: 10 seconds waiting.
nextavenger, sometimes the prob is not in your hand resp. on the table but between the ears or behind your eyes? Just a guess though ...

I have no problem with the phone. I own two iphones too. I am enjoying my Diamond more than these iphones. When i had picked this phone, i had never intended for Gps feature but moving to a new city all together, i figured the gps can actually help me.
I went through all the previous threads complaning about the Gps lag and gps problems before starting this thread. Its not only me who is facing a problem. I did a complete research before starting a new thread. I bought maps specially for this and if the device doesn't work out of the box, its kinda sad.

it is not diamond's problem, gps is great in there !

When I bought my TD the GPS worked perfectly. Then i start flashing various roms and radios, and began experience various problems. Hard to get fix, losing signal and a huge lag.
Finally i flashed the new official rom 1.93 with radio 05 and all my problems disappear. Now it works great. It takes only seconds to get fix and the signal is rock steady, and the lag is no worse than other gps units i have before.
Try Duttys newest rom, he has integrated the radio and rom in his download. He thinks that flashing radio and rom at the same time may cure the gps problem, and i think he is right.

I flashed dutty's latest rom,did a hard reset and my gps gets a fix in a matter of seconds.

for everyone who has gps problem, follow these steps and reset gps data:
1) remove battery for five minutes
2) install gpstest 1.04 and set it to com4 at 4800 baud
3) wait for a fix in an open space (about 3-4 min.)
4) exit the program and start tomtom (set it on integrated gps) or other navigation software and here you go!!!
These steps help everyone who has gps problem after installing, removing navigation softwares and works with every gps.
I hope this will help you. Bye.

Is it working yet ?

ok so i did this thing:
Flashed my phone using Swift's recent rom i.e v5.5
Hard Reset
Setup my phone
removed the battery for 10 mins
installed GpsTest
Loaded Google Maps
and voilla! its now working. Gps is locking fast too.

this is the best gps a ever had (except the SIRF in the XTEN until it quit on me)
from day 1 my gps worked fine with the usual lag. changed radio and flashed a custom ROM (see my signature) and no more lag.
i can guess looking at all the gps threads (i think there are more threads on this subject than threads on new ROMs) that there is a problem. i just don't understand why so many ppl has it and so many don't
btw, i am using iGO8.

Never had a problem neither with my Diamond. On the 1.37 ROM with .03 radio it took my GPS between 15 - 30 seconds to get a fix after a cold start. Which I think is already quite fast. Now on the 1.93 + .05 on a cold start I'm able to have a fix in 5 seconds more or less. I'm really amazed! I loved my Diamond already, now I love it even more

Pity you can't retract the heading of your thread....
My GPS works great also. No lag, fast locks.

You might want to download "htc gps tool". In that one you can do a warm reset on the gps, and that sometimes solves a gps problem.
Just dont run "clear storage" option in the program as you then have to restart, download quick gps settings, and restart again.

GPS icon/menu not visible, fix with ROM?

Hi all,
First off i'm a newb.
Second... I just got my phone though my GPS doesnt work (got tomtom). I then realized there is no GPS icon/menu to tamper with to change settings (all this talk about comm 4 and stuff like that).
Im going to "Hard SPL" the device, then "Flash" it with the Dutty 6.1 ROM.
I've checked all over this site, but i've not found a simple solution to my problem.
Is this a fix? (sorry for having no idea what im doing)
Thanks for reading.

navigate to start>programs and you'll find an icon called QuickGPS. Click on this icon and download GPS data, this is needed to get a faster fix with TOMTOM.
Next, navigate to start>settings>system>external GPS choose com 4, in the hardware tab choose GPS hardware port 7, and baud rate 9600, in the access tab, tick the manage gps box automatically.
Start tomtom and configure it accordingly...

still no luck
Thank you for your advice though still doesnt work. I have GPS test, ad when i run it it just stays on "GPS starting up" and on teh botting some numbers appear and dissapear.... and a tiny red line above it...
Do radios have anything to do with the GPS? If so could you recommend one?
thanks again.

yes radios can worsen or make the gps fix faster. and it all depends on where you like and what rom u install. I am currently using radio niki KAIS_Radinly_1.65.24.36_ CustomRUU with ROM 3.29.DK.10 and i get a gps fix under a min. I am in Rhode Island usa. East Coast.

First thing, DO NOT mess with External GPS settings. It is well known to hose the GPS.
Download QuickGPS (google for it) and let it run for a few minutes outside. Maybe as long as 5 minutes, but it should never take that long (although it's widely reported to take a long time for the GPS in the Tilt to warm up).
If QuickGPS still does not get a lock on satelites, then TomTom won't. But it sounds like you're probably not waiting long enough, particularly the whole "there's no GPS icon" thing in TomTom.... I suppose it's possible you've gotten a version of TomTom which doesn't work with the Tilt.
There's no need to install other ROMs or Radios to use your GPS.

Diamond + TomTom = semi-functional GPS (not a lag problem)

I have been using TomTom7 on my diamond for almost a year. First several months it was working fine, just some lags or freezes on roundabouts, which was not a big issue.
Then it started doing this strange behaviour at some occasions: I start TomTom, it finds satellites fairly quickly, I start driving, all fine. Then after some distance it loses coordinates (you can see the blue arrow, but everything behind it is grey and it is not following the route). Sometimes it fixes itself for a short time, then does it again. Sometimes this is all, whatever you do (reroute, restart tomtom, restart phone) it won't come back. Some days none of this happens.
Nothing in configuration had changed, I've been using the same radio and rom for almost a year.
I was really annoyed by this, could not simply rely on tomtom. Now I updated the ROM, and yesterday this happened again
If this was discussed before, please point me in the right direction, most of the threads I found by search were about lags or configuration.

It might be the Quick GPS Programs, I recall having a simular problem where the GPS would work for about 5 minutes then turn off, only turning the phone off then on then running up tomtom again would get another fix, only for it to run for a further 5 mins or so.
I think I disabled the quick GPS in the registry using PHM registry editor or something simular.
It might be worth considering updating the ROM. I'm running BsB's which seems much better than the stock offerings.

I've also had this problem with the latest rom from HTC (regular rom) with the radio 1.09.XX
I've updated to radio 1.15 and the problem is gone.

Thanks for you replies.
I've now updated the radio to one of the latest (1.09.25.23), the ROM was already recent (2.07 Gen.Y). Will test it during the week.
The solution based around disabling of Quick GPS - wouldn' it make the start up time longer ?

I have tried to install this radio, but got "Invalid Device Id" message, 1.09 installed with no problems. The phone is security unlocked, could not understand what was the issue and just moved on .. :-/

Could be error in timezone
Hi all,
I had a similar problem and it appears to be the timezone, by reasons unknown my Diamond was set to a timezone of Stockholm, now that looks ok, but it is not a normal timezone.
I changed it to Stockholm, Berlin, ... the standard timezone and once again I got a fix fast and easy.
The thing that you get a gray screen is that you our somewere in the middle of the earth according to the GPS, you notice this if you could see the coordinates and altitude.
I have iGo in my Diamond, but the problem was the same when using Google maps so it wasn't a problem with the program.
I have also changed my iGo to have a manually selected time zone, because I'm not sure if it might be iGo that made the change for me.
But now all my GPS works splendid, and I have a fix within 15 seconds.

i do have similar problems.. but it only happens when i'm in the dense core of downtown toronto where all the tall buildings are..
I think it's because the tall buildings are blocking the signal somewhat that is why your GPS kept on running out or coordinates and relocating itself again

I am in rural Scotland actually, the only high buildings here are castles which are miles away .. so this must be something different.
Neither it seems to be dependent on the sky nor battery level ...
p.s. testing new radio, so far so good ..

Just some feedback from testing: the original problem seems to be solved, but now I've got something much worse - sometimes TomTom freezes several second after the launch, and nothing can be done apart from restarting to bring it back. Don't know if this is a radio's or ROM's issue as I have changed both. Reinstalling TomTom from .cab did not help.
Anyone had similar experience ?

Hard reset maybe will help

Yes it may, but 3 days before holiday I do not want to be installing everything from scratch. I could try another ROM too if not this.
Tried - atifix, starting with bluetootsh on, wanted to reconfigure GPS setting in TomTom, but can't get there yet ... must be either BT or GPS connectivity

Updated radio to the latest 1.15.25.14 with 1.15.25.35 rilphone, made no difference at all ..

I think I found it - G-Profile service was the cause of the problem. Once I stopped it, TomTom has got 100% starting rate. It's a pity, was a nice small app to have.
