The Rosen AV system is what I have in my 2015 Genesis 5.0. Looks OEM.These cars have active headrests so you don’t want to cut into the headrests or replace them with aftermarket style
You are going to want to install a piggy back system that attaches to the head rest bars or the seat itself. Something similar to these:
Rosen AV7700 Headrest Piggyback System (Black)
Thank you. You can also swap out the " control box" under the seat with the Rosen headrest units to add HDMI inputs that allows you to use a Amazon Fire-stick or other USB type of media system if you do not want to use DVDs. My system uses the older non-HDMI box with RCA inputs, but it is a simple plug and play box swap if I decide to upgrade later without needing to upgrade the monitors..That looks awesome!
