Anybody out there having compatibility issues between the LR4's Bluetooth and the iPhone 3GS? The problem manifests itself as follows: LR4 and iPhone are linked. Incoming phone call is picked up by the LR4's Bluetooth and I hear ringing through the car's audio system. I use the car to answer the call. At that point, the iPhone and the LR4/Bluetooth disconnect (Note: the call is not dropped) and I have to pick up the iPhone and take the call from the iPhone. Land Rover's website seems to indicate that no firmware revisions have been tested with the 3GS.
