d) Connection of the Speakers and the Power Supply
Vehicles equipped with an ISO plug can be connected directly to the ISO connection terminal if
the plug assignment is the same (please check beforehand!). If the plug assignment differs, use
a vehicle-specific adapter from a vendor for connection.
Please refer to the following figures for the contact assignment of the ISO connection socket of
the car radio. Please ask your car dealer for the respective assignment of your vehicle system
plug.

The constant current te12 V (4) must be connected to a cable that also supplies
+12 V permanently when the ignition is off (terminal 30 of the on-board network). This
terminal serves to save the user settings, time, etc.
•
The aerial control output (5) supplies a voltage of +12 V with the device on. This cable can
be used for the power supply of an electrical aerial as well as for the voltage for switching
on a car amplifier.
