I was really apprehensive when I discovered that Sync was powered by Microsoft after I purchased my Focus two years ago, and rightfully so. What did MS know about maps and routing? On reading the article's subject my first thought, too, was I wonder if there will be an update: probably not.
Here are a few examples.
Found that the voice commands lacked synonyms so one had to conform to Sync.
It would lock up quite often for no apparent reason and the only way to re-boot it is to go to the side of the road, park, turn the ignition key to off, and then open the door for a few seconds. One could then restart and it would re-boot.
On the occasions when I needed routing my wife and son would be reduced to hysterics as I tried to get it to give directions to the intersection of, say, Laguna Canyon Road and Pacific Coast Highway. It appeared that it didn't like street names of more than one word in this context.
Use voice commands to make a call (this and some other errors of the type were repeatable) "Call Jenny Rechel home". Response was "No home number for John Litton, cell or work?"
I took it to the dealer twice and got updates that have stopped the lockups and can now use it to call Jenny but some other, more fundamental, problems persist.
