I am looking for a FBAS to RGB converter, small size, low cost.

Background: Back in the day and until 2008 BMW used to use RGB as the video standard in its cars. Three separate wires, red green and blue, would connect all video equipment in the car. Immediately after that they started using FBAS which consists of 3 wires again, but they are denoted as FBAS+, FBAS- and FBAS Shield.

Motive I want to upgrade my BMW video/TV module to a newer DVB-T2 module. Unfortunately these newer modules output FBAS, but my head unit and rear screen are still expecting RGB. This is why I need a mini and low cost FBAS to RGB converter.

A quick search has revealed to me the following:

"Composite Video (BAS / FBAS):
The (F)BAS signal is transmitted in an unmodulated form and consists of a brightness and synchronization signal, in case of FBAS also of an extra color signal. The transmission of the analog video signal is carried out via a RCA (Cinch) or BNC (bayonet) plug connection. "

Source: K238 Media- / DVI-Converter 7.1.6

I am wondering if BMW's FBAS is what they say above. Also in my search for such converter many sellers sell devices with Video/AudioL/AudioR (Yellow/White/Red) as being Composite, but this is obviously not what BMW FBAS is!

Can someone more knowledgeable tell me what converter I need to buy (small & cheap) in order to convert the BMW FBAS signal to RGB?

  • Straight electronics and potentially where to buy, isn't it? So rather electronics.SE,but I doubt they will like it.

    No, EE.SE will not take "what to buy and from where" type of questions.

    Why is that “obviously not what BMW FBAS is”? Anyway, probably best to enquire at e.g. Bimmerforums
