I have wiped and installed lots of TomTom One's and various Go's. My own go 910 however is giving me grief.
I had NC 9.485 installed and working for ages on this. I recently got NC 9.510 and installed this but had issues with the voices so have tried reverting back but now I am stuck on the splash screen. I have formatted the device under Windows as FAT32, tried 9.510 with no luck (just hangs at splash screen), tried 9.485 and again just hangs at the splash screen.
Its been a while since I did a full format and reinstall but I don't remember any issues like this previously? What am I doing wrong?
