t  On vehicles fitted with telematics system, activate the service mode for the telephone/telematics control unit -J526- before disconnecting battery -A- → Chapter.

All radio systems -R- are encoded so they recognise the instrument cluster (anti-theft coding). When removing and installing the same radio -R- or instrument cluster and after disconnecting the power supply, it is not necessary to encode the system.
Radio generation II+ is fitted from week 45/06 onwards.
These radio units receive their signals via two internal tuners with “phase diversity”.
The further design corresponds to that of “symphony”.
If the display shows the message “Transport” after switching on the radio -R-, you must deactivate the transport mode → Vehicle diagnosis, testing and information system VAS 5051.
