WARNING: This page is about a different car, the 2003 Ford Thunderbird. However, it is still accessible from the selected car via links, so may be relevant.
The audio system is enabled when the key is in the RUN or ACC position. The center imaging and subwoofer speakers are powered by their own respective amplifiers. The rest of the speakers are powered by the audio unit. The steering wheel controls send information to the audio unit allowing the driver to adjust various audio controls. The audio unit contains an integral six-disc CD changer that is not repairable. The antenna isolator module reduces interference thus helping to create clear sound when the radio is in use.
