ConsumerAffairs.com is reporting that General Motors cut off onstar service to customers with analog equipment on January 1 and after midnight February 18, the analog cellular network was shut down, rendering the equipment in consumers' cars useless.

Cellular telephone companies are no longer required to provide the analog service the older OnStar systems employ. This is the latest step in the transition from analog to digital communications sanctioned by the Federal Communications Commission.

If your car or truck is a 2002 model or older with an analog-only OnStar system you have probably already figured
out the system is kaput. Now the analog-only systems are officially useless unless the consumer was able to purchase a system that GM could upgrade to a digital connection and the consumer paid for the upgrade.

General Motors made digital upgrade kits available to consumers who had active OnStar subscriptions. Roughly 90 percent of the GM analog OnStar systems were capable of being upgraded to a digital connection.
