Tom Tom not playing

I finally picked up my MH after the fiat recall, (another story for another post) and when I turned on my built in satnav it could not find my current location this has happened in the past but normally in a few minutes it finds a satellite and gets going.
This time after several hours it still couldn’t find my location. I tried re setting it both on the move and static and I checked with my phone Tom Tom which is working fine.
I tried a factory reset but it’s still not working, any ideas or suggestions please?

Jami if I were you I'd phone the UK customer support tec,s .I found them to be to be great and new there stuff.
My start 20 lost its mind after an upgrade the day before we went to France last year, I called them while queuing for the boat and he emailed me a link ,which with the WiFi on the boat I was able to get it sorted ,he even came back to me to check it was working.

When our van went in for the same recall the power supply was disconnected immediately upon it entering the workshop,the reason I know that is because we only agreed to take our van to Donnellys Mallusk when they had the parts available and they drove it directly into the workshop. While returning home we received a call from Scorpion tracker inquiring if we knew why the main power source had been disabled. We informed them of the scenario and all was well, but could this be anything to do with sat nav becoming disabled?

Jamie I was thinking more along the lines of could it have been an extended period of no power going to the sat nav causing it to totally malfunction.

Neither I will look into this. Many thanks
