Hi, I have a 2000 BMW 7 series with the factory fit nav. However upon start up the screen says 'Please Wait' and stays like this??? the disc is loaded and the system recognises its loaded. Any advice would be real helpfull

Pull the fuses to do a total down power,leave them out for 10 mins and then reboot, see if that helps.
