Thanks. That link didn't register since I don't have iDrive/Nav. Interesting to see it though and great for people that do, for sure.
I'm driving an e82. Not sure if that makes a difference in terms of what wiring is there. Certainly in one three series, a lot of wiring was present but needed to be hooked up: http://www.e90post.com/forums/showpo...9&postcount=58
but I haven't seen any similar post from people driving the 1 series, like me.
But after re-reading those threads, for a non iDrive vehicle, it seems like the install requires a mic and a bluetooth antenna and coding, regardless of whether I buy a Combox or use the existing MULF.
