CarPlay Fun

Hrmm... That's a really annoying flaw. I use CarPlay a lot for Music and Navigation. I also use the SD Card as Video source for kids in the back seat. Those are the main reason for me buying the 8100nex head unit. To say that I can use one or the other, but not both simultaneously really sux.

What are you trying to output to the rear? Audio or Video? First confirm that both rear audio and video connections are made Second, what did you select as your Rear Audio/ Video source?
