Basically everything works without a dealer coding. I had to swap some wires in a plug because my MIC was not working, but after that it works great.
I think my total cost was around $400....not too shabby, but I really needed to have bluetooth for living in such a large city. Next satellite radio and iDrive if I'm feeling crazy.
