Hey guys. I tried this when I bought my 08. The dealer said they couldn't add sync. I wanted sync and satellite radio, so they found one we liked that had sync and added factory Sirius. A good option might be a Pioneer F700bt. It's a touchscreen navigation system with a usb connection, and built in bluetooth. It uses voice commands just like sync. The voice it uses even sounds alot like the voice sync uses. It would probably save you some bucks, and would certainly be easier to install. Plus it does more.
