Thanks for your reply. I tried everything. TTActivator doesn't recognize the TomTom and the same problem is with the TTMy Drive. Therefore I can't do anything. There is no connection.When I try to connect with My Drive it says: Your system does not react.
On the TT Activator it does not sees the Nav4 (TT).
The problem first began when I tried to update My Drive. TT does not had enough memory.
Therefore I deleted some files and the problem began thereafter.
