I installed a double din stereo in my Jeep, but I’m having an issue. Sound is great and all that but it has a day/night mode that you can press that keeps going off and on. This is the 2nd unit that does it. The first one did it as well. Is there some wiring I have missed? It’s not like the alternator kicks on and it goes dim it’s random. It’s just a generic head unit. No idea what to do, instructions are no help.
