Hello I just purchased the "Video Interface with HDMI for Audi MMI 3G.." I have few questions about the Can-Bus wires.
Am I suppose to splice the can bus wire into the harness?
There are 2 grounds (Batt, 12V), can i combine the ground to 1 grounding point?
My car is 2014 Audi A4 with the MMI 3G+
Thanks
Sunny
