Decided to add a secondary screen, so far the best add-on!!
both of the screens are android head units

Can be done to any Renegade.
its permanently mounted, but i can remove it and put new vent cover, they are cheap on ebay!!
nothing to worry about, sun or heat wont affect it, that's jut a screen, and since its a big concern for you, its not a big deal for me, ill buy another one!! the whole thing cost $60~$100!!
how i did it?

• cut and fix the screen on the vent cover
• extended the cables, i used long ribbon cables from lcd to the motherboard that i installed under the vent behind the main head unit
• wire it and its done, i only needed power, i could wire the car speakers to it and switch between the two but i don't need that, its mainly for gps, camera, inclinometer..
