Problems due to incorrect cable connections
In some types of vehicle, the default assignment of permanent plus and alternating
plus has been exchanged by the factory for the ISO block A in the ISO plug. 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 (alternating plus) and the yellow cable (permanent plus)
will need to be reversed in the ISO block. The specialist dealer has the appropriate
adapters for this.
