My TomTom One started acting up this weekend. I went to turn it on and when it booted up it went  to a black screen with white  writing. I shut it down and rebooted it and since then it continues to display "waiting for a valid GPS signal". I downloaded the QuickGPS fix but that did not resolve the problem. I even tried  resetting the device to factory settings and that did not even work. I left the GPS on while traveling for 3 hours and it never located a valid GPS signal. Any help or suggestions would be greatly appreciated.

Okay. If you use the 'Operate my TT' feature in TT HOME, it fakes the GPS fix. So probably, it does not have a real fix. That also explains the fact that it has no fix when disconnected from the PC. Have you tried to reset the device using these steps: http://uk.support.tomtom.com/app/answers/detail/a_id/6965? If nothing helps, you could delete all the folders on your TomTom (except for the map folder and its contents). Then connect to TT HOME and let it update the device.  Do you still have warranty?

    When you place the device outside in the open air for 15 mintues, does it find a GPS signal then?

    Yes, that was in the vehicle. But have you also tried it in the open air, so outside the vehicle? If even that does not work, I think the GPS receiver is broken.

    Yes, I have tried it in all locations (in a house with a mouse, in a box with a fox...LOL!!) It locates a valid GPS signal just fine when I plug it into my computer at home and operate it but as soon as I unplug it goes back to waiting for a vaild GPS signal. Any suggestions if the GPS receiver is broken?

    I just did the reset procedure following the steps listed. It appears to be stuck in the black screen with white writing. I received my TomTom One for Christmas 2009.

    You could try to reinstall the software. Here, we normally have two years warranty. I don't know how long it is in the US, but you could try calling TT.

    Only a 1-year warranty on TomTom models in North America. Sadly.

    I did that downloaded QuickGPSfix and it did the updates, but still no satellite detection. I did the setting it outside for a while, didn't work. The odd thing was it worked in my house night before last then the next morning it had no signal and I've done everything since and nothing. No signal. Where the satellite things are I tap on that and it goes to where it shows the satellite stuff is and it shows several full but says signal poor. I've only had it for 2 years but I use it at least once a week. I just don't think it should be worn out so soon. I wish some one could tell me something I haven't tried. Thanks for getting back to me.

    Ok, I went to a reply that said delete all folders except the maps folder and I did and set it outside for about 5 min and now I have a signal. HURRAH !   !   But now I have no other symbols. I hooked it to my computer and clicked on up date and it said no updates available. Should I restore it or will that put it back in the shape it was in where it couldn't detect a signal? What do you thing?

    What do you mean by 'no other symbols'? Maybe it's possible to just restore this 'other symbols' from the backup and keep the GPS settings/files of your current configuration.

    I meant for the car symbol. I tried what you said about just installing what I wanted from the back up. You can't do that. I did decide to try just restoring the whole thing, figuring I could re-delete it, I did that and for some reason it works perfectly now. Go figure !  Anyway it works now so HURRAH ! Thanks for your help. You are in the Netherlands? I am in Washington state.  Thanks for being there !

    Are you talking about a GPRS of a GPS signal? Because this topic is about GPS signals, not GPRS signals.

    I have a similar issue with No GPS SIGNAL FOUND.  How do you reset?  I have read that you hold down the power button for 15-20 seconds....is that all you do?  My TOMTOM was working well from VA to SC yet when turned on in SC there was "NO GPS SIGNAL"  hasn't worked since. Any thoughts?

    Make sure you have tried the following items in this link.

    http://us.support.tomtom.com/app/answers/detail/a_id/6964/kw/gps

     

    If you are still unable to resolve the problem the next step is to uninstall and reinstall the software in the gps.

    Here are the steps for that.

     

    First: make a backup of the contents of the gps using windows explorer. Per this link.
    http://www.tomtomforums.com/general-tomtom-discussion/17864-how-backup-contents-your-unit-computer.html

    Second: check the flash memory in the gps to make sure there are no errors.
    http://us.support.tomtom.com/app/answers/detail/a_id/9908/kw/memory%20error

    Third: If the memory has no errors or they were repaired by the check disk utility you just ran, uninstall the software on the gps and reinstall it.

    http://us.support.tomtom.com/app/answers/detail/a_id/2053/kw/reinstall

    Note: when reinstalling the gps software you may have to perform up to three updates to get everything installed. The  gps may not work correctly until all the updates are installed. With the gps plugged into the computer just reset it to get the gps to connect to the computer and perform another update.

    Forth: If the gps is working now, there are a few misc files like startup / shutdown screens that you can copy back to the gps from the backup copynyou made. Here is a list of those files. Just use windows explorer to copy them from the main directory of the backup to the main directory in the gps.

     1. antitheftw.bmp   (this may have the named antitheft.bmp)
     2. autorun.inf
     3. splashw.bmp      (this may have the named splash.bmp)
     4. suspendw.bmp     (this may have the named suspend.bmp)
     5. tomtom.ico

    If everything is working ok now we recommend making a final backup of your gps. That way if something happens in the future all you have to do is delete everything on the gps and copy the backup to the gps and you are done.

    yes davidhum, I have many thoughts about this, but without any proof, so it is purely speculation. My ONE XL worked perfectly for about 2 years, found the GPS in seconds. Then I made the major misrake of connecting it to my PC and updated the SW as suggested. From that very moment it behaved as decribed an many forums. It can't find the GPS signal, but my spartphone and a Garmin 5 inches away can. It loses contact if I stay in the same position for more than 5 minutes and then drive on, it loses the connection out in the open country for no apparent reason, and come back after 2 minutes or one hour, maybe the next day afdter being turned off. Absolutely useless. Unfortunately it is not possible to reload the old version of the SW, which actually worked. When trying to report the problem I am told that my device is an old product, and that I can go elsewhere for help and support. I do. I go to Garmin, and advise everybody I talk to to do the same. Planned obsolescense ?.
