2001 X5 OEM Business Radio/MID, no DSP, non nav.
Unable to set clock, cannot switch between AM/FM, cannot change disc selection in the CD Changer.
Clock only allows minutes and year to be changed using the buttons.
I had this problem a couple of times and cured it by removing radio & MID from the vehicle. Once reinstalled the full functions were restored however not this time. I even changed out the Business Cassette tape player for a used Business CD player to no avail. The problems started when the vehicle had to be jump started.
