so I have question here, for older models which directly PNP, when you adjust interior light brightness (illumi), does the dynavin button brightness changes as well? Hot about the screen brightness? Because I just thought about it, if I plug the illumi wire to the taillight, then it will stay at the brightest part and won't change when I adjust with the stock illumi switch. If it doesn't change then I'll just leave it, if it does, guess I have to re-wire it to the illumi switch.
Also I am playing around with the unit, how do you adjust the screen brightness? I found the adjustment page in setup, but when I change the volume of the brightness number, the brightness doesn't change on the screen at all??????
