There are two antennas fitted to the vehicle, an AM antenna and an FM antenna, both are located in the rear windshield glass. The AM antenna is above the heated rear windshield element to the left-hand side. The FM antenna utilizes the heated rear windshield demist element but does not carry the demist current. The power connector to the demist screen has a filter in line called a positive wavetrap and the ground connector to the demist screen has a filter called a negative wavetrap.
An optional diversity FM antenna is available with the premium sound system, similar to the AM/FM antenna, except that three FM antennas are derived from the demist pattern. As the demist screen is split to create the extra antennas, a double wavetrap is fitted which has two positive connectors. The antenna isolator switches between the three FM inputs and sends the strongest to the radio.
The antenna isolator module controls both antennas
