I have the RBZ and it works great. Strangely enough though it would not download the music from my iPod via the USB port. Whereas the 09 I had did it just fine. Mine also has the Uconnect which works great for me. If you're wanting the Sat and Uconnect functions, make sure you get all the parts needed to make them function.
