Hey there guys - great site. Look forward to reading everything here. I just bought a 2007 [new body style] crew cab Z71 4x4 LTZ package.

I looked at several and drove a few and one thing they all had in common was they had XM installed with the nav / radio unit. My dealer finally found the color I wanted [greystone metallic] so I bought it last night. Now I'm not sure if this one has XM or not. There is no XM option on the nav/radio unit but I have the little shark like fin antenna on the roof - isn't that the XM antenna?

Thanks,

 

Congrats on your new ride
