Does any know if it is possible to install a 2007 or 2008 stereo headunit in a 2006? I was looking at the parts and part numbers online and the only difference I see is the output and the AM button on the 2006 panel is a SAT button on the 2007/2008. Has anyone tried? I found a 2008 headunit and I am contempalting trying it. I know it may be more than installing an aftermarket, but I like the idea of OEM.
