I'm new here as a poster. Followed the blog for a bit though. My first question is how do I know what trim package I have? I have a 2010 Nitro w/ 4WD. No cruise, power windows but not seats. My second question is, I have upgraded my stereo to a Kenwood and it offers vehicle info... ie... tires, temp, malfunctions, that sort of thing... has anybody else got this to work? Its the Kenwood DDX9703S. I have been doing lots of upgrades. Next is aftermarket cruise.
