I have tried to restore my unit completly, and have come so that when i turn on the unit i have to press the menu button to get screen up.
But when i try to enter any of the navi og navi settings, the unit shows the warning screen wich i press OK, but then nothing happens.
The phone, AV Source and AV settings does not work also.
Do you have any pointers on what is wrong.
Restored the unit from full back up and copied over files in testmode.
