Service department did great job. Unable to resolve one major issue though. It is a GMC issue that I���ve read about. Paired my iPhone with no problems. However, the volume on my iPhone turns down as low as it will go. It does this automatically, as soon as I get into the car. When I leave the vehicle I miss calls and texts because of this issue. I���ve never had this problem with my Toyota vehicles. It���s really a nuisance. I will NOT buy another GMC because of this problem!
