The "RDS radio" system uses the heated rear screen element as the radio antenna. The signal is processed by an amplifier before being passed through to the head unit. This antenna and amplifier is also used receive and process signals from the remote handset to lock/unlock and arm/disarm the alarm. Because of this there are two types of amplifier to accommodate the different frequencies used with the remote in different markets. This standard amplifier is located in the tailgate at the top left hand corner.
The "RDS Hi Fi" system uses a second antenna fitted in the left hand window of the luggage compartment to achieve the diversity function. The amplifier for this antenna is located in the left hand side of the luggage compartment behind the trim panel near the wheel arch.
