They do have a compatibility guide ready to download at http://www.landrover.com/ca/en/Owner.../Bluetooth.htm
The problem I have run into is they do not support any smart phones (Blackberry's, Treo's, etc) unlike the Range Rover and LR3, which I am very annoyed over. They told me to buy a new phone and they'd give me $100 gas card!? I'm not sure what to do as I would have not gotten the technology package.
If you learn anything, let me know. By the way, I have the Blacberry 8700.
