My 2007 LJR steering wheel was a mess. Gooey and old. I found an EBay seller with reconditioned TJ steering wheels. Great reviews so I bought one. The steering wheel is an exact replacement but it has factory volume controls. My understanding is that US Jeeps in 2006 did not have volume controls although the steering wheels have the indentation for them. Any ideas? Is this a European wheel as the seller is from Europe? How would I hook up the volume control electrical? Thanks for your help!
