CAN bus
In many vehicles, speed, reversing and light information can be read out from the ve-
hicle’s CAN bus and converted into the appropriate signals for the navigation system
using an adapter.
Universal installation
If none of the above-mentioned options are possible, the wheel speed can be con-
verted into a digital speedometer signal by means of an MA 3400/00 magnetic field
sensor and magnetisation of a tyre.
■
Reversing signal (A2):
☞
Connect pin A2 to a suitable reversing signal point (positive lead of reversing lamp).
✎
Operation of the navigation system is possible without a reversing signal. The ab-
sence of a reversing signal may lead to inaccurate navigation.
■
12-V ignition positive (A4):
☞
Connect pin A4 to a suitable 12-V circuit via the ignition.
A
This connection should be rated for a current of at least 10 A.
■
Electronic antenna/ motor antenna (A5), optional:
☞
Connect pin A5 to the supply lead of an electronic antenna or to the control line of
a motor antenna.
A
Do not use this connection to power the antenna motor.
■
Pilot lighting (A6), optional:
☞
Connect pin A6 to a suitable connector of the low-beam positive lead.

When the low beam is switched on, the pilot lighting at the volume control is illu-
minated, even when the radio is switched off.
■
12-V permanent positive (A7):
