The radio receiver located in the luggage compartment is the receiver for navigation unit information. The radio receiver then sends the information received on to the colour monitor.

The radio receiver is supplied +30 from fuse 23 in the dashboard main fuse box and is grounded in grounding point G40-42. It is supplied +B and +15 from a special switch for nav/tele.


The radio receiver is the distribution centre for the entire system. Calculations made by the navigation unit come first to the radio receiver, which in turn further distributes all data and signals.
