2008 Silverado LT2 package

[namasil04]

On 2008 Silverado with LT2 package, onstar is located behind the lower trim panel (just below the radio and a/c). No need to remove the trim panel around the radio. Simply pop the lower panel above the center console out, and the module is right there. 15 minute install time max. Very easy. Please take the time to look here before removing the dash, radio, and a/c controls.
