A little while ago we reported on BMW using Google Maps to help motorists who might be directionally challenged. These BMW owners can conduct a trvael search on their home computer and beam the destination straight to their Bimmer. It makes entering the destination into the car's navi unnecessary and the whole process a little safer and error proof.

Well, now we can officially declare this a trend between mappers and automakers. GM has teamed up with Mapquest to allow Turn-by-Turn Mapquest search results to be sent directly to an OnStar-equipped vehicle. According to the press release, "This new Turn-by-Turn service enhancement, OnStar Web Destination Entry, will allow subscribers to conveniently use MapQuest.com to research and plan their driving destinations with more than 15 million points-of-interest available through the number one mapping Web site." More than two million 2007 GM models will get the upgrade and another 3 million will be added in 2008. The service upgrade will start with a pilot program this summer and will be opened up to all OnStar subscribers with Turn-by-Turn navigation-capable vehicles by the end of the year. In the interest of full disclosure, AOL is the parent company of both Weblogs, Inc. and Mapquest.
