When I bought my sat nav Tom Tom version 3 it worked fine. The second time I used it I now cannot pick up a GPS signal at all. Tried Reset and a Factory reset. Can any help?

Um. I guess its may be because your at location wherein sat signals are week or other case could be when person relocate to other countries and if sat nav was bought from previous countries wherein its meant for to use then this happens (i personally experiencing this) . Sometimes magnetic environment factors can cause disruption in signals.

Hello there,
First of all, what you need to do is to reset the device. To reset the device fold a paper clip and use it to hold down the reset button for about 5 seconds. The tomtom tom will be reset. Then you power it on, then go to settings, then you select the sounds, then turn on the sound. And increase the volume.
The sound will work perfectly fine after doing this.
All the best. Elect_Comp

try to plug it in and keep it out in clear sky or all the way upfront of the windshield may take up to 10 min

If the maps are on an sd card you may be able to put tom tom on but as for updates myguide no longer exist and so don't provide updates. Mine still works fine and any roads that have been built that don't appear on the sat nav i have managed anyway.

It isn't the sats. They're fine.

Try resetting the unit. Use a paper clip to press the button in a small hole on the bottom.

Try to reset the sats. To do this:

Tap the satellite bars in the lower right-hand corner.

Then, on the next screen, tap the satellite bars in the right-hand margin.

On the next screen, select "Configure." Choose a different configuration. Tap "Done," then "Done" again on the next screen.

Did that help?

try downloading tom tom home to your computer and use your dock or cable to connect it to your computer, switch on your tomtom and allow it to connect to your computer and updates should automatically happen, this should fix it, good luck

My tomtom one screen kept showing that it was waiting for a valid gps signal all day yesterday 7/1/09 what can I do to fix this problem?

Think I have sorted the problem out. I read some of your readers' solutions and it was mentioned that it may be advisable to log onto the GPS update. So, I installed my disc which came with the pack and followed the instructions to download the GPS update (and also took the opportunity to download other updates which took some time). Anyway, used the sat nav this morning and so far, it appears to be working normally now and the signal comes on in seconds!

I had the same problem after downloading the latest maps, the unit was slow to boot up and would not find any satelites. I had no response from e-mails to Tom tom tech support and I was going to give up and buy a new device if this fix failed. I had tried paper clip resets and resetting to factory settings but they had not worked.

After reading the previous answer to this link I searched Tom tom support for 'clear flash' and the search results were more useful than the FAQ on the normal support pages.

I used Tom tom home to uninstall the current software application and then reinstalled the latest version (I had to go through several updates as my version of the software was from when I purchased the unit in 2007), I then downloaded and ran Clear flash and made sure that I disconnected the tom tom from my PC using the correct procedure (using the eject button in the bottom of the tom tom home screen as I read that this could have contributed to the problem in the first place).

After another reset the device came to life and after a few minutes searching for satelites outside the device worked as it should (try checking the configure GPS option if it is taking a while to find a signal, it could be just me but it seems to speed up the search process).

Hope this helps.

I just connected to my computer and ran updates that I got from tomtom.com... It works fine now. Try it with the new software.
