Thanks Andrea. Spoke with Darrell who was very helpful. I had not appreciated that the Bose system option (which I have) runs a different Nav package, and the offer only covers the non-Bose (Marelli) system. There is no update as yet for the Bose, but when it comes out Darrell says they will run the same offer. So i didn't pursue the question of how you know which version you are running....but did have a very useful chat with him about some other aspects of the Bose system which I'm grappling with, and following up with his technical expert (as usual, the ICE stuff these days is much more technical than the whole physical engineering!). Thanks for the link.
