GM doesn't look to be letting the prospect of a huge chunk of its customer base disappearing
stop it from rolling out enhancements
to its Onstar
service, with the company today announcing that it's struck a deal with MapQuest that'll see the two services linked up. Under the new arrangement, OnStar users will be able to plan out their trip on the MapQuest website and then follow along in their vehicle using OnStar's turn-by-turn audio navigation service, with them still able to call up the help of a live advisor if they really fall off course. Not everyone will be getting the expanded service to start with though, with a pilot program encompassing some 3,000 users planned for this summer, followed by a full roll-out later this year or next once they've gotten all the kinks worked out.
