d) Connecting the speakers and the power supply
Vehicles equipped with an ISO plug can be connected directly to the ISO terminal (21), provided the same plug
configuration applies (please check in advance!). If the plug configuration differs, a commercially available vehicle-
specific adapter should be used.
Contact assignment of the ISO terminal (21) can be found in the following figures. Please consult your car dealer
about the respective assignment of your vehicle system plug.
Terminal B (speaker terminal)
1 Rear right speaker (+)
2 Rear right speaker (-)
3 Front right speaker (+)
4 Front right speaker (-)
5 Front left speaker (+)
6 Front left speaker (-)
7 Rear left speaker (+)
8 Rear left speaker (-)
Terminal A (power supply)
1 not assigned
2 not assigned
3 not assigned
4 Continuous c12 V
5 Antenna control output
6 not assigned
7 Ig12 V
8 Ground
•
The continuous c12 V terminal (4) must be connected to a cable that supplies 12 V permanently when the
ignition is off (terminal 30 of the vehicle electrical system). This terminal serves to save the user settings, time, etc.
•
The antenna control output (5) supplies a voltage of 12 V when the device is on. This output provides power to the
DAB antenna and a car amplifier. The thin black wire of the DAB antenna is connected to this output.
•
The ig12 V terminal (7) must be connected to a cable that supplies 12 V only when the ignition is on (terminal
15 of the vehicle electrical system).
Do not connect this terminal to continuous current; otherwise, the vehicle battery could get discharged
when the vehicle remains parked for a longer time.
•
Connect the ground connection (8) to the vehicle body.
Adhesive techniques that evolve and the painted metal parts impair the electric conductivity. Therefore, not
every metal part is a suitable earthing point.
