For those who got here and found out that 2 wires need to be connected manually (CAN-H and CAN-L), there's an article from Paul O'Brien called Carplay Upgrade for VW Touareg where he shows how to find those wires. In my case (2013 Touareg), the wires are orange/green as CAN-H and orange/brown as CAN-L. With them connected, everything works fine!
Wow, terrible installation video. Poor camera angles to see what’s demonstrated. Did no show that part being installed. Worst installation video Ive seen.
The RNS850 has always had a full color screen... If you insert a DVD into the player, you can watch a movie (not 4K). It will also display MP3 song info in color if the info has also been imported with the MP3. The NAV screen is color as well.
