Hi there. I have a 2009 Saab 95 bio power wagon. I have installed a pioneer nav system in, and it works fine. However I'm having trouble getting the axxess swc to work. The swc unit is powered and can reduce the volume level when I switch the car, but cannot get the steering wheel buttons to work. Can someone please help me determine which wire it is I need to use as the control. Pink is the wire on the axxess unit, and green is the colour I was told to use. But I get nothing.... First time forum user, so please go easy on me and my ignorance...
