I recently bought an 01 X5 4.4i.

Turns out the MID has been swapped out and the current one does not offer the BC button, nor the other functions that are associated with the proper display....ventilation programming, etc...

Anyway I am now in the market to get the proper MID, at a minimum, one that includes the BC button.

Anyway, how do I know if I have the DSP option?
There is a black amp mounted in the rear of the vehicle (no changer).

Also, when I run my VIN (LH17798) it says I have "Hifi Loudspeaker system" and "Radio BMW Business."

Thanks all.
