I had an ebay MMI for my ccc nav and used an android set top box. The MMI connects between the nav controller and the screen and it hi-jacks the signal to the screen for a video input. The problem with that was the MMI has only a composite input and the ccc nav screen has low resolution so the image quality was not great at all. It worked great for years but I wanted better quality.
A few months ago i installed the bimmertech vividscreen which has hdmi inputs and a Hi resolution screen (replacement). I purchased a new Android box so it has been a completely new upgrade. As far as I know, the vividscreen is only for the ccc system.
I'm not sure what is available for CIC nav systems, but the would be good if you could find a device with an hdmi input.
OP, that replacement screen looks cool but I would be hesitant what android is like. Does it have the play store? Is it rooted? How is it controlled? ...just some things that come to mind.
Crappy picture attached but you get the idea
