WARNING: This page is about a different car, the 2007 Saturn Outlook. However, it is still accessible from the selected car via links, so may be relevant.
The main amplifier power is provided by a 30A fuse located in the under hood fuse block. For vehicles equipped with UQA, the radio commands the amplifier to perform the following functions through serial data (GMLAN) communication. The radio controls both the overall muting and the rear seat muting via serial data (GMLAN) messaging.
