I have an 08 - I bought the Isimple ipod kit from ebay.

works great w/no issues whatsoever.
Only down side is that you have to remove your unit to plug the wire in the back of the stereo unit.
I didn't know how to do that so I paid an installer to do that for me.
However, there's been several posts since that shows how to remove the stereo.
If you don't want to go that route, another member posted his install.

he went thru the XM module..real easy install.
Ipod adaptor is a MUST.
Good luck.
