I have a few problems when I replaced my old Symphony, 25 watt per channel radio by Alpine with an aftermarket navigation system.
Everything works fine, except that my steering wheel controls don't work and the buttons of the unit don't light up when I turn my headlights on.
Here are a few videos of the cables and the wire diagram front the unit.

The cables that are not wired from the grey connector are:
Blue/Orange, Blue/Grey(or brown), Red/White and Yellow/Brown.
The Red cable is connected to the Green/White, the black one is connected to black and the yellow is connected to Brown/light brown wire.
Thank you!
