NAVIGATION SYSTEM Speaker Circuit

DESCRIPTION

If there is a short in a speaker circuit, the stereo component amplifier assembly detects it and stops output to the speakers.

Thus sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier assembly, telematics transceiver* or speakers.
