Ford Sync at CES 2010 -- Very Slick, but iPhone Offers Only Partial Support
Microsoft and Ford were showing off the third version of Ford Sync at CES, and Casey and Phil from Android Central and I jumped in and got a demo. The good news is that it works great. It plays your music, makes your phone calls, and alert the authorities in case of accident, and more...
The bad news is the "and more" doesn't apply to iPhone and iPod touch owners since Apple hasn't properly implemented all the Bluetooth control protocols. Also, SMS to voice isn't implemented for the iPhone, and I'm guessing that has to do with the current SDK as well.
Still, the system looks slick and solid, supports multiple phones and music players, and lets you focus on your driving rather than fiddling with your devices. As more places make hands-free mandatory, it's also going to be increasingly important.
