I am going on a road trip with a bunch of guys this summer and was hoping to set up some old gaming systems in my suburban. I have a 2018 with a screen in the middle and a screen in the back. After looking in the manual and online it appears that there is only 1 hdmi port behind the center console. The older module suburbans at least hat RCA ports in each of the dvd/ blue ray players in order to hook up gaming systems to. I don't understand why chevy wouldn't see that having 2 HDMI ports, one for the back and one for the middle would be desired. Please help me to figure out this problem and or inform Chevy for the future. Thanks
