Hello, the gps signal is not working on my tom tom one n14644. I've tried numerous attemps to find the signal, but I am unsuccessful, can you guys help me?

I am glad to HELP YOU!

I'd suggest you - first thing first - to make sure your TomTom device is getting the proper signal. Maybe in the area where you've tested it are too many tall buildings or too strong magnetic fields. So I'd say to get your device in a park or even outside the city/town limits and to retry to acquire the satellites signal.
If you will have the same result that will lead to the opinion that the GPS receiver itself it's damaged and must be replaced.
If your device is still under a warranty terms & conditions - then take it back to the dealer and ask for a total replacement or for a total refund. DON'T TRY TO FIX BY YOURSELF THE GPS RECEIVER! It's too fragile and maybe you will end up with a useless device...!
Anyway - before any attempt make sure your TomTom battery IS FULLY CHARGED!


My best regards!
