last year they made a big stink at Blackberry World Expo that they were going to do some kind of integration with Jaguar there the cars screen will mirror the phones display, and you can control it through the car.

i guess the whole thing got scrapped

My guess is that because RIM (now Blackberry as of today) has basically self-destructed, there wasn't a large enough user base to justify implementing it. I monitor the mobile space at my company and made the recommendation to eliminate Blackberry from our environment last year, so we are actively replacing 2000+ devices with iPhones around the globe.
