I have to chime in here.
I have the HTC Windows Phone 8X and it dovetails into Sync flawlessly. Anything I can do with the phone I can do through Sync (receive and send txt, bluetooth my music, etc, etc).
I've always felt that the limitations with Sync are more with the phone and not so much with the car. Maybe its more so because they both runn MS Ops?
