Greetings! I am looking to purchase a 2013 or 2014 NV 2500 S with the power package. All of these that I've seen don't have the audio steering wheel controls. I was wondering if the wiring for the controls exist behind the left side of the steering wheel, or are they just not run? I will be changing out the head unit and would put in a module to allow the steering wheel controls to work. The reason I was looking at the S rather than the SV that probably has this already is because I don't want a center console, I do want the chair arms, and everything else I am going to do for the conversion doesn't need any of the SV features. Any thoughts or ideas? I'm assuming that if the wiring is there that I could purchase the panel for the steering wheel that has the controls on it. Thanks! --Zeke
