I've had my TomTom since Sep 07. After a couple of months it became really slow when starting up and a few weeks later stopped searching for satellites. To get it to search for satellites I have to restore factory settings and reset (this doesn't always work either). Have sent it back to TomTom once nad they returned it saying there's nothing wrong with the device. A colleague has the same model bought around the same time and his takes approx 30 secs to start and a further minute to find satellites (I can drive from Kent to Derbyshire and stil not find a single satellite). And no I don't have an aethermic windscreen. Since TomTom can't find a fault what do I do (other than buy another sat nav)?
I have a tomtom XL and for the last two days it is not picking up satellite signal, I do remember that the message was being displayed " file error unable to store settings "
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.
Try this. Download the tomtom clearflash from tom tom and save it to your desktop. After download is complete run the file and then follow the instructions.
Sometimes the flash doesn't clear on the tomtom and you will get errors. This will clear your flash.
Hope this helps

I would send it back to tomtom again and tell them it is definatly not finding satellites. Hopefully they will find the fault this time. if you prefer not to send it to tomtom but have it checked somewhere else , then maybe you can search online with google as I know there are at least 3 places to have it looked at but I won't mention them here as its not a forum for advertising. There are several reasons why its not picking up sats but there are 3 most likely causes. A/ Contact with top antenna board has become broken / unplugged ~ tomtom one and one V2. - B/ Ribbon cable has become unplugged ~ tomtom Go - C/ software faulty or faulty sd card . ......... Most likely cause is faulty file on SD card .
