Installation and Removal
The unit can be installed in any ISO installation slot. Please 

contact the car manufacturer or the local dealer if your 

vehicle does not come with an ISO slot.

 

Before installation remove the two transport securing 

 

►

screws.

Connect all cables before mounting the unit. Ensure 

 

►

all connections are correct and the system works 

properly.

1.  The set is designed for an installation where the nega-

tive pole of the battery must be connected to the 

vehicle chassis. Please check this before installation.

2.  Please note for installation/connection of your set 

that not every vehicle is equipped with an “ISO 

connection”. In this case we recommend the use of a 

vehicle-specific ISO adapter.
Adapters are available from car accessory sellers and/

or your car workshop.

3.  The connection of “Continuous +” (continuous cur-

rent connection) may differ depending on the vehicle 

type. (However, this is required for storing of the radio 

stations.)
In order to assure all functions, installation according 

to these instructions is necessary. In case of doubt, 

please contact an authorized car workshop.
Because of the different vehicle types and vehicle 

manufacturers, correct wiring of the ISO connector 

is no assured even when the ISO plug connectors fit 

mechanically. Thus it may be necessary to change the 

electric connection or to use a vehicle-specific adap-

tor.

 

In case of correct connection, the radio can be 

 

►

switched on and off with the ignition. In case of 

possible loss of stored radio stations, the radio is 

not provided with the “Continuous +” required 

for station storage.

 

In case of connection to “Continuous +” without 

 

►

ignition, an unnecessary load may be caused for 

the car battery even when the radio is switched 

off. In the worst case, this may lead to discharge 

of the car battery.

4.  Depending on the vehicle type, interferences may 

occur during operation of the radio. These can be 

eliminated with an additional noise filter. Your set is 

already equipped with a noise filter as standard. In 

spite of this, interferences may be caused depending 

on the vehicle. 
Noise filters are available from car accessory sellers 

and/or your car workshop.

5.  When installing your radio, take care that there is 

sufficient free space at the rear of the radio to assure 

sufficient cooling.

6.  There are two different standards for the antenna 

connection. The first one is the old one (50 Ohm) with 

a long projecting round contact on the vehicle side 

and a round socket on the radio side. The second one 

is the ISO standard antenna plug (150 Ohm). Adapters 

for both formats are offered by car accessory sellers 

and/or your car workshop.

 

To be strictly observed for VW/Audi: The antenna 

 

►

of your vehicle may be an active antenna. This 

requires a voltage supply only provided by the 

original car radios. If this should be the case, 

please use an antenna adapter for phantom feed. 

Antenna adapters are available from car acces-

sory sellers and/or your car workshop.

The correct tools are self-explanatory for a car hifi
