This review is from: PAC OS1 OnStar Interface For Select GM Vehicles Without Bose Systems (Automotive) I had replaced the stock radio in my 2001 Suburban and had mixed results with it. At times, the built in stock amplifier would not start and there would be no sound. At other times, it would start without any problems. I finally read where the PAC OS1 OnStar Interface would fix this problem and it has. It has been well worth the money to have the radio working every time I start the vehicle for the last 40+ days.
