Hi,
Just got a 2018 Yukon Denali XL with rear entertainment package. I've been trying to play movies from my Iphone and Ipad through HDMI. I got a lightning adapter to HDMI and plugged my Iphone in to it, and the HDMI cord to the adapter and to the HDMI port on the back of the center console. So the movie on my Iphone plays on the second row and third row drop down screen, but there is no sound from the movie through the car speakers and you can only hear it through the wireless headphones. On the main head unit when I press video the movie does not play on the screen even when the car is in park. It won't play on the main nav head unit up front. It does the same thing when I try and play netflix from my Iphone through the HDMI cord. Does anybody know what is wrong or if I am not doing something correctly? Any help would be great! Thanks!!
