for Volvo (during the procedure «serial number assignment»),
Only optical connector

It is necessary to register in the configuration of the vehicle using the diagnostic
To connect the adapter, you will also need an optical cable with connector (not
Notes for BMW: an additional mode of the adapter (BMW spec.mode (park)). This mode
should be used if you want to change the volume of the signal (parking sensors and system
messages). Read more about this mode in the Applications.
Notes for Mercedes Benz (only for Comand NTG2.5):
– It is necessary to activate function “Rearseat entertainment”.
Notes for Volvo and Land Rover (if you have activated component protection):
Before connecting the adapter must be assigned to the adapter serial number (a marker of
activity of the protection components is the cessation of broadcast audio adapter in 20-40
seconds after turning on the system).
For the assignment you need to set the jumpers to position «Read Serial Number», then,
not disconnect the original amplifier, connect the adapter to the optical interface MOST and
turn on audiosystem. After you enable the adapter «read» the serial number of original
amplifier and store it in its non-volatile memory. This procedure usually takes less than 20
seconds, a sign of the end of the procedure «Read Serial Number» is the formation of pulses
with an interval of 1 second on the line Remout (blue wire). After that you should disable
original amplifier, set the jumpers to a position corresponding to the car and use the audio
interface in the system instead of the original amplifier.
