Is there any way to turn of all or some of the retained accessory power (RAP) options? I want to kill the power to the 12v outlets when the Enclave is off if possible. I have an FM tuner plug in for my iPod. With RAP it will stay on indefinately I think. Will the 'save the battery feature' prevent this? It didn't seem to in my previous Chevy Avalanche. Any suggestions? ???
