seeing as those guys say they have a 'module'...<br> <br> After seeing pics of the MCS in the Nav install docs, I can't imagine where they would possibly add a composite video input to the MCS.<br> <br> Think about it - if they were to get the arrows working to switch between video sources, it would either mean that:<br> <br> a) They managed to convert the MCS to some other market MCS, which allows for video input.<br> <br> b) They've hacked the MCS software, and added the required composite inputs, and software functionality.<br> <br> I highly doubt they've done either. Does anyone know if the MCS allows for an input video signal in other markets, and if so - if the arrow keys are used to designate the source displayed on the screen?<br> <br> Wish I could find a beat up MCS to play with.... Anyone know the hardware platform for it? (processor, OS (if applicable, probably some form of embedded RTOS). For all the work people do dumping timing chips to enhance engine performance, I wish someone would dump the MCS for a quick looksee...
