I'm selling my SIR-GM1 Sirius radio tuner. I bought this to use in my old Trailblazer and the new one has it from the factory. It works great and will add Sirius to your truck while using the factory controls from the radio, so no ugly tuners stuck to your dash. It also comes with the original packaging. It works with Class 2 radios and I believe they need a Band button. It will work with newer radios with a different harness, but I'm not sure where to get it from.
