Nice! That's the route I'm going to go. Installing factory nav at this point is costly and lacks the technology the new head units have, for sure! Nice work! You went all out with the headrests and all I see! Doing the backup cam is so much easier with a new unit, all of them have leads on them ready to go.

How good does the BlueTooth work for hands free calls? The factory BT unit in my E38 works well most of the time.
