MFD 2 radio navigation system
The MFD 2 radio navigation system does not
feature an internal diversity tuner. It has an
external tuner, to which two rear window aerials
are connected.
On the MFD 2 radio navigation system,
a shark-fin type roof aerial is installed.
For reasons of safety, a specified breakage
point is integrated in the design (red line).
If the aerial breaks off, there is a risk of water
ingress.
If a vehicle is ordered without radio
system or without radio preparation,
only the rear aerial structure is
provided. No provision has been
made for connection to this structure.
