Let's see if i have this straight. You have a 2007 X3 (still under warranty i presume) and you removed the original audio (Business CD) and replaced it with a Kenwood flip-out, rear camera, bluetooth and nav.. Correct???

That means you replaced the Manufactures gear and installed after market gear correct?

Now you expect the dealer to use BMW diagnostic gear to diagnose your X. Is that correct?
