Offering the ability to track family members out driving, General Motors is rolling out testing of a program called OnStar Family Link. The initial test group takes 10,000 U.S. OnStar subscribers and gives them the ability to check their vehicle location on a Web-based map. The test is currently invitation-only, but GM claims that the service is accessible to all 6 million OnStar subscribers. The service is likely compatible with OnStar FMV, an after-market installation of a custom rear-view mirror that uses the OnStar service, but isn’t being tested yet. This attachment sells for $299 and subscribing to OnStar service costs $199 a year.

There’s no pricing attached to OnStar Family Link and it’s likely to be bundled with the current subscription plan of $18.95 a month. The service is likely to by popular with families, especially when tracking drivers in difficult weather conditions. Another use could be watching the progress of a family member driving to a relative’s house for Thanksgiving dinner. Testing of the OnStar Family Link trial will continue through late September 2011. At that point, General Motors will decide if a national launch of the service will become available to all OnStar customers.
