OnStar is going to go all-digital sometime down the road, leaving any analog system users out of luck. The change primarily affects anyone who owns a pre-2002 GM vehicle, some 2002-2004 GM vehicles and some Acura, Audi, Subaru and Volkswagen vehicles with built-in OnStar. It’s a result of a small 2002 FCC decision allowing cell phone companies to shut down analog networks beginning February 2008. Dealers will upgrade some GM 2002-2004 if customers buy a three-year subscription at $199 a year. Otherwise, analog OnStar users will need to convert to digital equipment, if it is even possible for their vehicle. About half of OnStar’s 4 million subscribers still drive vehicles that cannot be upgraded. And, oh yeah, the FCC decision will affect cell phone users, too. At least a cell phone can easily be replaced – Hey, it’s yet another reason to keep readin’ Gadgetell!
