My unit is a coolpumpkn KD-D1908 for a suzuki grand vitara.
The button lights are always on when the unit is powered on and they are always brighter than the surrounding lights.
Also there is no way to turn them off or dim them with the vehicle dimmer.
Iis there a hardware or software way to enable dimming.
My first idea was to disconnect the led positive lines and connect them to the vehicle's illumination wiring. Since its all 0-5v it should run the stereo led's just fine or i'll have to use a voltage converter to get the right brightness to match the rest of the surrounding lighting.
I think the only wire on the head unit for illumination has one function and that its an input to the mcu that in turn sends a signal to the rk3188 to dim the screen according to a preset software amount. So that's only an on and off setting.
I'm just looking for a way to make this unit behave like the factory unit :)
Thanks.
