When the rear window defogger switch, which is built into the multi-media module display assembly, is operated, the operation signals are transmitted to the A/C amplifier assembly through AVC-LAN and BEAN. When the A/C amplifier assembly receives the signals, it turns on the DEFOG relay to operate the rear window defogger.

without Navigation System:
When the rear window defogger switch, which is built into the integration control & panel, is operated, the operation signals are transmitted to the A/C amplifier assembly through AVC-LAN and BEAN. When the A/C amplifier assembly receives the signals, it turns on the DEFOG relay to operate the rear window defogger.
