It's weird the cars they identified in the list, the 730d would share the same,e hardware as the 6 Series and indeed the 5 Series, and I'm sure there's not a specific system for the 30d over any of the other 7 series.mthe system they describe is frighteningly simple when I think about it. No different really than an RF signal booster used by mobile operators in certain circumstances.Originally Posted by eddiem74
