I have SX4 2011 and changed the factory radio to Pioneer AVH-X4800BHS. I'm trying to install ASWC-1 Axxess Steering Wheel Control but I have a problem...
In the paper installation manual the control wire of the ASWC-1 is Green and should be connected to pin 11 on the car's wire harness. At the website installation manual the control wire of the ASWC-1 is Gray/Blue and should be connected to pin 19 on the car's wire harness.
For both manuals:
Red wire of the ASWC-1 should be connected to 12-volt accessory wire, one that turns on and off with the ignition key (pin 2).
Black wire of the ASWC-1 should be connected to ground (pin 20).
Anyway I tried both ways but still it don't work. When I turn the ignition on, the led of the unit start flashing rapidly, after few second I can see 6th led flash in Green and 6th led flash in Red after that I can see on my radio the "volume symbol" for few second but the buttons on the Steering Wheel doesn't work at all, after that the unit start flashing Green/Red, and that's it....
Could you please help me with this problem?
I checked pin 19 usually is 0V but if I hit the brake it's becoming 4-5V
