I just took my car in to Wakefield Sandall BMW to have the Alpine upgrade fitted, and they called to say they can't fit it as it is not compatible
Car is a 335i - the guy said it was because I had the "DSP" option and that was taking up space where the amp would go, and that the DSP has its own amp and is not compatible with the Alpine.
I presume by DSP he means Digital Radio?
Any of you guys done such an install? Is it not possible to fit with the DAB radio?
Got the professional sat nav and head unit.
