I actually sold my M5. If your unit has DSP you have to do one of the work arounds. I'd suggest following with blkxer did exactly. His setup was perfect and clean. My unit was an android version and worked well till the day I sold the car. The metrics unfortunately are there to stay. The reverse sensors did work in the car. The screen updates kind of slow when you are backing up (i only had reverse sensors on my M5) which could be a hazard. I purchased an e60 M5 and it has this same feature on the idrive and it updates super quick and all of the sensors are extremely accurate. All in all the unit was some what cheap and the menus didn't all match as I felt they should have for nearly $1,000 a unit. That's like buying a pioneer unit and just cutting your losses. You shouldn't have to do that. The units were all designed for non-dsp cars. If your car has dsp you might want to wait for them to refine it more or explore other options (of which i'm sure there are still none as good as the dynavin).

Let me put it this way... they now make units for the e60 series... My oem setup has okay nav, very few POI, and no 3d buildings. It can't play DVDs and it barely can play MP3 CDs.... Yet I have no desire to install a dynavin unit (at all). I would rather spend 3,000 and install a 2010 oem e60/e65 CIC nav system. At 3X the price it'll retain the OEM features and I won't have touch screen, but it's something I would prefer. Different strokes.
