Here is a really good video showing the Ford Sync feature installed in a, of course, Ford.

Ok, it's a good video, it's a good feature to have in any card but... I still think that FORD means Fix Or Repair Daily. The last FORD I owned was about 8 years ago and after paying more than 1500 dollars in just one year of repairs and fixes I swore not to buy any more a FORD or any other made in USA car. Sorry Microsoft but you got the wrong partner.
