I have a 2016 Suburban LT that has 2nd & 3rd row screens. The rear seat entertainment console has a usb slot, RCA inputs (yellow, red & white) and an SD card slot. I had a neat idea of putting an old sega genesis in the back for the kids to play on trips but i can’t figure out how to access the RCA input. The only media options to choose from are DVD, usb, aux and SD card. Has anyone dealt with this issue?
