2008 X3 radio/nav controls inop

Was driving our 2008 X3 and the radio suddenly went dead and the radio and nav controls stopped working. Back-lit is still working for the controls, but no response. Tried turning car off. Checked fuses. Even pulled the radio out to verify connections (as best I could).

Any other thoughts or ideas? I am thinking about ordering a replacement for the radio unit, but I don't know how to verify the part number.

It's the top one in your picture but they are superseded all the time.

Before you swap your head unit, pull all 3 fuses related to the radio and reinsert. I bet one has slightly jiggled out.

I know you tried already, but I have had this happen to my 09 navigation unit while one morning about a year ago. Same issue...back light on lcd, no sound, display or audio. I forget which fuse but one had worked loose and wasn't supplying enough voltage to the radio. I pulled all the fuses one at a time in my work parking lot and the last one being pulled and reinserted did the trick. No problems since.

The boardmonitor is just a display and a keyboard. The radio is located in the trunk, along with the nav drive and tv tuner (if fitted) that do the image generation.

There is a fuse in the connector of the tuner module.

The radio makes a little orange triangle appear on the bmbt when it is on and playing.

The radio will shut off after a few minutes if there is a problem with the iBus

The bmbt screen backlight should work if it's powered up.

The blue socket on the nav drive can be moved to the TV tuner to swap which unit does the image generation.

Thanks for the info. I will give it another try. Are you referring to fuses in the glovebox area or in the read of the vehicle? Thanks again

In the glove box.

Pulled all possible fuses and replaced without success, so I wound up replacing the head unit. Got a Scosche VW/BMW wiring adapter on eBay and a pioneer stereo from Crutchfield that came with a faceplate for the X3. Took under an hour to install. Works great. Wouldn't give it great grades on appearance, but with 90k miles the vehicle doesn't deserve anything better. Then I disabled the old nav by pulling the two wiring harnesses from the nav drive in the rear quarter panel.
