I have a Tom Tom ONE Classic.
When I connect it to the computer I get a message "Do you want to connect it to the computer", I answer yes, then nothing appears to happen.
While it is connected I cannot use the GPS.
When I disconnect I get the message "writing route information".
Is this expected functionality. I had hoped for some UI on the computer to be able to see what routes had been updated etc and be able to use the GPS while it is charging.
