Has anyone installed a SIR GM1 in a Chevy Trailblazer with factory XM radio ?
I'm curious how difficult the installation was.
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?
Because my name is on the business, I work hard to make sure you get the best possible shopping experience. I look forward to hearing your comments .
