Go over your wiring again. On that note, where did you get the wiring directions from? Maybe they are not accurate. If that is not the case, did you buy any modules that will keep the steering wheel controls and the On Star working correctly. I did that on my 2003 when I bought my JVC KW-NT3HDT.

 

ModifiedLife is where I got them and I Dnt have steering wheel controls

 

What power wire are you using?
