Hello, I will do my best to help answer your General Motors Vehicle questions.
Try rebooting your vehicle.
Disconnect both battery cables positive then negative.
Connect both cables together away from the battery for a minimum of 30 minutes.
This will drain all energy storage capacitors in the modules.
Reconnect positive then negative last, making your last connection as quick as possible to avoid voltage spikes.
Allow five minutes before you power your car to on.
Try your radio/cd player.
This corrects many issues that can arise from a battery change.
