For the IBUS, I got my self the Resler IBUS interface
(IBUS Interface for BMW cars) (v5, USB link)
FTDI components are not available here, niether melexis, so
it would be better to just get it from him, He is a great guy to deal with btw.

as for the video interface, i tapped into the video module (with TV tuner) and used the Reverse Camera inputs just as most setups out there.
I also bought a VGA to COMPOSITE adapter which went for about 40 bucks i think.

If you want i can get you the brand/link for the VGA converter because it doesn't come to mind at the moment.
