Antenna System

WARNING: This page is about a different car, the 2018 Cadillac XT5. However, it is still accessible from the selected car via links, so may be relevant.

Multi-Band Antenna

The multi-band antenna is located on the roof of the vehicle. This type of antenna is primarily for cellular and GPS signals, if the vehicle has these features. Keep this antenna clear of snow and ice build up for clear reception. If the vehicle has a sunroof, the performance of the system may be affected if the sunroof is open. Loading items onto the roof of the vehicle can interfere with the performance of the system, ensure the multi-band antenna is not obstructed.

Diversity Antenna

The diversity antenna system uses an antenna integrated into the rear spoiler. The antenna receives both AM and FM signals, it may also receive DAB signals if equipped. The antenna amplifier receives the signals from spoiler antenna. The antenna amplifier is connected to the radio by a coaxial cable.

The radio antenna amplifier is enabled when the radio is turned on. The radio provides battery voltage to the antenna amplifier using the center conductor of the antenna coaxial cable. When a 12 V signal is seen by the amplifier on the center conductor of the antenna coax, the received signals are amplified.

When the AM band is selected on the radio, the antenna amplifier connects the AM antenna to the radio. When the FM band is selected, the antenna amplifier provides FM signals to the radio.
