Ok here's the problem, after I installed the HU, everything is good until today when I was driving back home. The hu starts blinks. It dims (normal) when I turn on headlight but blinks (light/dark) when the headlight's off. I unhook the illumination wire and everything is good but no dimmer function. Once I hook it back, it just starts blinking again. Anybody can help? May it be a battery problem or something?
I tried hook the alpine illumination (orange) on both dimmer(orange/white)/illumination(orange) wire on the factory harness, but still the same problem. The thing really annoying!

try tweaking the brightness level of your dash lights with teh **** by the gauges. sometimes when its on the voltage borderline, the headunit cant make up its mind
