VICS Module
WARNING: This page is about a different car, the 2008 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
The vehicle information communication system (VICS) module, an export only dealer-installed option, uses signals from the optical/microwave beacon antenna and the rear glass VICS antenna via the TV antenna module to convey routing information to the navigation radio. The navigation radio either revises planned routing or relays the VICS information to the operator through the screen of the navigation radio and the voice guidance system.
