Yes this has happened a few days ago. I have not done any updates, the car is still new since June. As soon as I start the car the Nav goes on and then reboots after some seconds, then it works fine from then on.
First of all Nokia C7 is not found in the list of mobile phones when trying to establish wireless data connection settings. The progress bar is stopping at 65% and is taking a long time when copying the phone book from mobile to tomtom.
