My ON-STAR will cease on 12/31/2007 because, it’s an analog system. Are there any upgrades to keep it working? It’s a 2001 Olds Bravada.
I’m sorry to say but no.
You’re going to be one of many who still have the analog ONSTAR system in their vehicles. And when ONSTAR switches to digital signals, the ONSTAR analog system will no longer operate.
There is no conversion from analog to digital signals on your ONSTAR system.
