Hey guys, I have had my GTS for nearly 3 years now and I had a Pioneer Avic-D3 installed shortly after. I have taken it to several shops to try and get the factory steering wheel controls to work using the PAC adapter and no shop I have found has been able to figure it out. I had downloaded the diagram from PAC for my year/model and the shops have all said the colors on the wires don't match up to the diagram. I am getting really frustrated and would love to get this figured out finally! Have any of you had any luck getting the steering wheel controls to work properly with an aftermarket Nav unit?

Any help is greatly appreciated!
