Navigation Question

[ffresh12]

Hey everyone. I just purchased a 2003 X5. It has the navagation system but for some reason it seems to not be working correctly.

When I start the car the nav lights up and goes to the "welcome/warning screen that you have to press accept to contine" but it wont go past that screen at all.


None of the buttons work besides the bottom left one which when I spin it, it controls the volume for the radio (which I can only change the station using the steering wheel).

Does anyone have any ideas of what would cause the nav to not work? Thank you very much. I thought I would give you guys a try before I bring it to the dealer and spend a lot!!
