Radio Tuner Calibration
WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
The Country Code option does not contain a submenu. Country Code sets the point of sale, or origin, in the radio in order to calibrate the tuner for the country that the vehicle will be used in.
To calibrate the radio, select COUNTRY CODE under the Special Functions menu on the scan tool.
