I want to retrofit a reverse camera into my e46 with MKIV Navigation and widescreen.

This link:

seems to imply that there is an OEM video module that is plug and play with the MIKV drive and has universal camera hookups...

Anyone have any idea what the part number of the system would be? If Bimmernav is charging $575 for it, I'm sure its list price is around $250...

Thanks!
