Installation
This relay cable can also be used to control an external amplifier. Please refer to
the amplifier's operating instructions for the correct connections.
Never connect the blue cable to the engine cable; this could damage the
radio!
Arrangement of the ISO block
Problems due to switched cables
In some vehicle models, the standard arrangement of cables [4] and [7] in the
ISO block A (see above, "ARRANGEMENT OF THE ISO BLOCK") is switched at
the factory.
If this is the case in your vehicle, certain functions may be impaired: stations may
not be stored properly, for example.
To solve this, the red cable (switched plus) and the yellow cable (permanent
plus) will need to be reversed in the ISO block.
