Using the MMCS LCD as screen for android auto (2014 model)

[sanzhar]

Hi All,

I was digging around and found a manual for MMCS W15(w12?) where I found this part: 890P19412 , M041 ASSY-LCD. A google search has not yielded anything useful... But I was thinking, can we perhaps "splice" into the wire that goes from MMCS to the LCD screen and stream our own video signal?

What I had in mind is have a raspberry pi with openauto running and then a switch which would alternate between the "stock" LCD signal (for all things MMCS + back-up camera) and whatever the pi is showing.

I scoured some russian forums but couldn't find anything helpful...

Thanks for reading

Without knowing what signals (LVDM maybe?) the MMCS unit outputs to the LCD, your best bet might be to fool it into thinking the car is in reverse and switching a composite video signal into the reversing camera input.

In the manual it shows rear camera connecting to NAVI Power 8P Connector, a google search doesn't reveal much... I'm wondering then, what would I lose if I replace the stock unit with something better? Remote timer I can setup via wifi app but for the rest?

Have a look at any of my posts about my set-up. I've a Pioneer double DIN and run the AppRadio Unchained app on my Android phone - full mirroring and control of the phone from the head unit, with steering wheel controls functioning (except voice command, which you can do from the head unit's button).
