I have Nav and DSP, it comes with a 4.8is, which is nice

Anyway, I have read the stereo articles many times, and I'm still not quite sure on how to accomplish the install. Either some articles skip some steps or aren't exactly related with what I'm trying to do.

I think this one is the closest. http://www.xoutpost.com/articles/x5/s...-x5-4-6-a.html

The unit came from my old E36 M3 which used a harness adapter from Crutchfield.
