He said that if I wanted a new stereo, it'd be better to just replace the tray with a new stereo, so that I'd have two. But even then, since the NAV is hooked up to the speakers, I'd be better off not getting NAV.

Also, he told me that even if I don't get NAV, to replace the stereo would be tricky because of the hidden cassette player behind the face. He said if I replace it I might void some warranty.

I'm not sure how much he really knew about, well, anything that he said. Does anyone know if any of the above sounds right? I'd really appreciate any light shed on the matter...
If you had a 330i or 325i I would probably have been able to tell you the score, but since you have a "ZHP" I'm afraid my advice would be quite invalid - sorry!

Go and have a look at the NAV (why capitals?) system and you will see what the dealer is talking about. The navigation system is integrated with the stereo - so if you get the navigation system you cannot then change the stereo because it *is* the stereo.

You can stick with the stock stereo (a CD player for US market) and get BMW's aftermarket navigation system. If you really must have an aftermarket stereo, you can then rip out the BMW CD player and stick in whatever you like. However you need to be sure that BMW's aftermarket navigation system will work with your chosen aftermarket head unit - otherwise you'll never be able to hear the navigation system, well, navigating you.
