I have an '05 ZHP 330ci with the factory H/K system, no Nav. I've swapped out the head unit twice. The first time was to put in a Kenwood Flip Out w/Nav, and then the second time was to put in an Alpine single din CD Receiver. My installer does not use any adapters, but runs the head unit directly to the H/K amp and it seems to work just fine that way. The sound is great and everything works just as it should, including the "audio expander" button. A good installer will know how to do this and it won't be an issue. And this should be the case for ANY aftermarket head unit as I was told.
