Sirius SIR GM1

  • Has anyone installed a SIR GM1 in a Chevy Trailblazer with factory XM radio ?

    I'm curious how difficult the installation was.

  • I found this customer review, and thought would be helpful for you. Its from one of our customers who installed the SIR GM1 in a Chevy Trailblazer.  It looks to me like it should be a reasonably easy installation. Keep in mind we will give you free tech support by phone if you need help, and it comes with a 30 day return policy.
  • I have been thinking of getting the SIR-GM1, but I have read numerous reports by Trailblazer owners with the nav unit who see the "XM ERROR" message on the screen sometimes when starting the vehicle.  The solution is to turn off the car, open and close the door, and start up again.  Is Crutchfield aware of this, and any resolutions?
