What year do you have?Do you have the connectivey option?

 

nice picture you have up

 

I could be entirely wrong...Here's what I think, you must have the conductivy option. In order to have that option you have to have Nav. If you want OEM full jag intergration of bluetooth and audio and don't have or conductivdy or nav, you must get both from a jag dealer, ebay, etc...It will most likely be cheaper to just buy a different headunit, yet it appears you will lose your steering wheel audio controls. Or you could get a stand alone blue tooth system which will NOT be audio intergrated, meaning you'd have to manually mute/turn off your stock stereo in order to hear and talk the phone...
