Hi everyone, I have just updated my TT1 with the latest available software v6.15 and it all works fine and I also updated my tomtom HOME desktop . However, the next day when I tried to connect my TT1 to the PC using the usb cable it would'nt recognize it as if it is not there. It would say "Please connect a compatible Tomtom device". Whereas before, it would auto-detect the TT1 and would show on the TT1 screen that it is connected to the PC. Can anybody out there help me with this please? Thank you very much.
