I recently sold my X5 so I have for sale a TVonNav (http://www.tvonnav.com/bmwtvonnav.html) wiring harness and the bmw video module, which I programed to work while in motion. It works great, you can hook up a dvd player to it and which movies while you drive or you can which tv, it also has a hook up to mount a reverse camera to it. The system works great. You can change the channels with the steering wheel functions. I am asking $600.00 plus shipping. What you get is
-the video module from BMW PN 6 923 418
-the TVonNav wiring harness
-the antenna which hooks up to the video module(it has two nicks in the wire) It worked fine, but you might want to replace it. update 8/20/07 I took it to local mobile audio and video shop and they spliced the wires and said it should work fine.

This is a plug and play system very easy to install. You DO NOT have to cut or splice any wires. I removed this from my 2001 X5 with DSP.
PM me with your email address for pictures and any other questions.
