Common Components
Both systems share some common components, these are detailed bellow.

Radio Module
The radio unit for the 'Low' system is located in the cassette, CD or Mini disc player unit. The radio unit for the 'High' 
line audio system is separate from the head unit and is located in the left hand side of the luggage compartment.

Radio Module

Both radio systems offer the option of Business units or Professional. Both units offer six preset buttons allowing the 
presetting of 6 radio stations on FM, 6 radio stations on MW and 6 Radio stations on LW to the preset buttons on the 
Multi-function Display . The “Business” system provides standard AM/FM tuner capabilities (RDS Traffic information 
Etc.) while the “professional”system has two separate tuners built in to give improved radio reception through diversity 
tuning. This involves one of the tuners providing the selected programme while the other tuner continuously searches 
for a stronger signal for the selected broadcast station and for other RDS stations that can be received.
