I have a 2015 Sierra Denali with factory RSE. Is there a way to add an HDMI port to this setup? I know it was mentioned above that it was difficult depending on the year, but the statement sounded like it was being made for a vehicle that didn't have factory RSE already installed...
If I already have factory RSE, is there a way to add HDMI (also read that it may be limited to 720p, which I'm fine with). I'd basically like to add a Chromecast for the kids. It's easier for a 4-year-old to control my phone than read through text menus in the factory system...
