Hi,

Last night when I first got in my x5(2001, 3.0), I noticed the button to open the doors doesn't work anymore. I turned the car off and restart it and the button works again. However, the date information on my Nav screen now shows "--/--/2006". I tried to re-enter the date but the computer just doesn't take it.

Does anybody know how to fix this? Or a trip to the dealer is unavoidable.

Thanks in advance...
