The situation is my truck is running, music off or on pause. I have two different switches, the first switch is just to turn on my dash lights, and the second is to turn on the headlights. When I turn on the first switch, the headunit gets dimmer. I was wondering why and if there is anyway I can keep it the brightness it is before I turn on the dash lights?
The headunit usually has a switch to dim when the lights are on so it doesn't blind you at night. Either turn that setting off on the hu or just cut/tape the wire
