I have a 2012 NON-MMI (Concert) Audi A5, with the multimedia buttons (volume up and down, scroll up and down, mode, and speech buttons). Does the video interface http://car-solutions.com/en/video-interface-for-audi-without-mmi-with-active-parking-guidelines.php work with the steering wheel buttons, specifically switching between the video sources with the MODE button?
I have found other vendor units that have this functionality.
Also I see 2 6.5" touch screen overlays (one looks to be flexible the other appears to be rigid) are these the ones that would fit the 6.5" non-mmi display in a B8 chassis Audi?
