I wired up my Z150BH unit and everything seems to be working well, until night time. The -+ and mode, map, etc... buttons are bright as all get out. I hooked the orange/white cable required to the lights wire on my car. The unit knows when the headlights are on and responds accordingly. The main display dims down into night mode and the info screen shows the headlights are on, but the button lights don't dim, aren't modified by moving the car light dimmer up and down. Is this supposed to work, are they not dimmable? It's been about 15 years since i last installed a head unit, but then i did it for work every day. So i'm not terribly new to this, but i just wanted to make sure i didn't do something wrong. Any advice would be great.

I know it's an old topic but to answer your question the Z150BH does not dim the buttons, just the screen. I haven't seen any settings or noticed mine dimming with the headlights, just the screen.
