Hi evereyone.
I recently wanted to update the firmware of my F500BT unit (EU version). Since I don't have installed any map update I seem to have downloaded and installed the wrong version. I upgraded from 1 to 4, now knowing, that 2 would have been the only verion working for me. Now the unit boots, shows the main menu and says 'System Startup in Progress. Please Wait' (for I have German as language it actually says 'Systemstart läuft. Bitte etwas warten.'). The message never disappears, but I can start navigation, the warning is displayed (with startup message on top) and thats it - no
