Antenna, Satellite, Audio: Operation

The antenna includes the following capabilities:

• Cellular  - The cellular antenna is an electromagnetic circuit component designed to effectively capture radiated frequency and transmit signals in the cellular broadcast bands.
• Global Positioning System  - The Global Positioning System (GPS) antenna is capable of receiving eight satellite channels. The navigation system requires a minimum of three satellite channels to provide adequate information to the GPS navigation unit.
• Satellite Digital Audio Receiver  - The Satellite Digital Audio Receiver (SDAR) antenna is part of the satellite audio system of the vehicle. This antenna enables the vehicle to receive signals from the Sirius XM satellite and delivers the signal to the satellite audio receiver.

The antenna must have open space in which to operate. Items carried on the roof, parking inside an enclosed structure or driving through a long tunnel can have an effect on the ability of the antenna to receive signals.

For information on diagnosing the satellite antenna cables using the (special tool #9977-6, Kit, Radio Antenna Diagnostic), and perform the. Refer to POOR OR NO SATELLITE AUDIO RECEPTION .Poor Or No Satellite Audio Reception  test.
