I stopped by a dealership today, and the salesman told me that if I get NAV for my 2004 ZHP, it would be pretty much impossible to replace the stereo with an aftermarket MP3/CD receiver. 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...
What are your motivations for changing out the OEM headunit? The only one I saw in your post was MP3. If that is the case, you have a couple of options regardless of if you go NAV or not that let you keep the OEM unit:

- Get the AUX-IN adapter for the head-unit. This essentially provides a line in to your stereo for any device such as iPod or XM radio etc.

- Add an Alpine MP3 CD changer to your car.

Search on this forum for the appropriate keywords, you will find tons of info. BTW: I've never seen a modern BMW with an aftermarket headunit that did not look like ass... keep the OEM headunit and if you want the NAV, get it... it is very cool.
