During my trip last week in Germany, the system failed, probably because of the GPS rollover...

At home I tried to up-date the Tomtom camper using Mydrive connect. Never saw the up-date of navcore only the GPS quick-fix. The system had several soft resets, the reset with black white screen 1-2-3 tap and direct connection with the cable (according to instructions totmtom).
Now the system is rebooting all the time. not reaching a nice start-up. the welcome screen is hanging and after some minutes black screen and again starting. I am desperate. What to do?
Anyone an idea how to get in touch with a helpdesk by phone? Anyone who can help me out?
