My steering wheel controls only work for volume +/-, track selection, and mode. The phone call and voice buttons don’t work. Also, none of my controls cause the buttons in the menu pictured to turn green. PIN 4 is for steering remote control which is connected. Furthermore, my green Phone call button (accept call) causes my system to mute.The photo shows the functions of the steering wheel buttons. The system menu has two options for the steering wheel buttons. Either by protocol or by learning. I have learning to choose.
Did you connect anything else, like the KEY1 or KEY2 wires coming out of the back of the unit? Any special settings changed?
