Not sure if this is the right forum. Anyway i would like to shut down my backup alert warning when i back my Acadia up to hook up my camper. The sound drives my crazy and i can't hear my wife yelling at me telling me which way to go to hook up (probably a good thing i guess). Also with the camper hooked up backing into a camping spot the thing drives me crazy. I know it's doing it's job, but i need to back up close to hook it up! So what do i need to do to shut down the system while i'm backing up with a camper?
