The MID is a simple display device...it doesn't need to be coded. And it appears you need a MID with the AUDIO button (no DSP) at the top and the clock-face & BC button on the bottom button since you have a X5 4.4 with high cluster. Really sorry that someone stuck that low MID in your X:
And as others mentioned...that is NOT a DSP amp in the pic you posted. A DSP amp has 3 connectors on the top instead of the single connector in your pic.
