Ok, so it seems that I managed to create an account without adding my device. Now I am trying to upgrade my Tom Tom Smart Media System maps using the SD card and the computer isn't allowing me to go any further without a USB cable. Anybody able to help me with this? I saw a video on youtube where the guy just popped the SD card into his computer and went into his Tom Tom account and all ok. This is all getting annoying. Am I missing something basic here?
