OK..thanks everyone. Here's where things are at:
1) Unit arrives tomorrow via Fed Ex
2) Antenna adapter - on way
3) Antenna 12' extension - on way
4) BMW harness - on way
5) PAC LOC - on way
6) Back up camera - do I have to use a Pioneer cam?

At this point the question I have is do I use the harness up front (recall I had OE nav display) or in the back where OE tunner connection is? Or do I just hack off the connectors up front and go with "trial and error" until I get somewhere?

Thanks again everyone...will have some pics once the project commences.
