Since Ford launched Sync v.2.0 at the Consumer Electronic Show this past year,  | | You'll now be able to add destinations while on the move, thanks to Destination Download. (Photo: OnStar) | it's become a bit of a battle between it and GM's OnStar system to see which in-car link is better. Sync's version 2.0 offers the ability to call for help if the airbags deploy via the user's Bluetooth-connected cell phone, and the ability to send diagnostics updates to the owner using the same means. This is in addition to Sync's voice-activated controls for navigation, stereo, and Bluetooth phone. OnStar, by comparison, uses a proprietary link that requires a monthly subscription.
GM is firing back with updates to its OnStar system that will make it more useful and user friendly. The first involves cars with a navigation system in the headunit. GM doesn't allow data to be entered while the vehicle is in motion, but, using OnStar, drivers can request "Destination Download", which lets the Onstar advisor display info about a destination right on the car's LCD display.

The next OnStar upgrade involves a partnership with MapQuest and is for use in cars that feature OnStar's Turn-by-Turn service in a feature called eNav. Prior to heading off on a journey, subscribers of OnStar can plan out their trip using MapQuest online, and have that data broadcast vocally via OnStar. eNav will be available to current OnStar systems.
Finally, OnStar will expand its usage of XM NavTraffic, allowing better coverage of traffic avoidance for those customers who have navigation-equipped vehicles.
