DVD Player: OnStar®
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
If the vehicle is also equipped with OnStar®, DVD audio will be interrupted during an OnStar® call. During an OnStar® call, the mute line is low, ground, and the radio switches to play the OnStar® audio to the vehicle speakers. In OnStar® AUX mode, the radio displays PHONE and the fade is fixed at full-front, balance control is fixed at center, and the tone control is fixed at a pre-set equalization. Volume level can be adjusted as needed or desired.
