You have Nav so you have the RF6 tuner. All you need is the OEM XM tuner and antenna of your chose. I have a post here or at CT with part numbers and pictures. Just click on my user name and check my post in the audio formals. Theres a bunch of install thread on this from others that well help you also. You can instill it yourself, no big deal and save yourself some bucks. Blue tooth is another ballgame, can't help you there. If you can't find what you need, PM me and I'll dig up the pictures for you and try too help the best I can. Good luck.
