Question .. Has anyone determined if the satellite radio kits avail for the 2005, 2006 3GS will work with the 2007 (as the 2007 has a 5th gen Navigation) ?? I would think its the same, but after reading some of the posts and pics, the nav screens seem a little different.

 

I just had my Lexus dealership install XM radio in my 450H. The Nav-audio screens are different, but I don't think that has anything to do with the XM kit compatability. I will say that the XM antenna just installed on the 450H is 75% smaller than the XM antenna that I had on the 2006 GS. The new antenna is less than a 2" square, and is barely noticable on the rear package tray.
