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.

As a result, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier assembly, DCM (telematics transceiver)* or speakers.

CAUTION / NOTICE / HINT

Note

When replacing the DCM (telematics transceiver), make sure to replace it with a new one (w/ Telematics Transceiver [for ERA-GLONASS] or w/ Telematics Transceiver [for G-BOOK]).

Tech Tips

Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Navigation System.
