my TT620 trucker has frozen on startup after support recommended a rest
it starts and I get the language scree, then the country and then the choose vehicle screen, but its a blank screen and wont go any further. My drive says its connected but it wont allow you to to do anything to the device as frozen I also get the message that the TT service are busy . Desperate as just spent $700 on this useless device and support just will not get back to me. Frustrated much. any advice would be welcome.
