The pin arrangement for the ISO connectors depends on the type of vehicle you drive. Make sure to make the proper connections to prevent damage to the unit.

Please be sure to reconnect the cable as shown 2 below to install this unit to the Volkswagen vehicles.

When the connection is made as in 3 above, the unit's power will not be linked to the ignition key. For that reason, always make sure to turn off the unit's power when the ignition is turned off.

To link the unit's power to the ignition, connect the ignition cable (ACC...red) to a power source that can be turned on and off with the ignition key.

Make sure that the unit is installed securely in place. If the unit is unstable, it may malfunction (eg, the sound may skip).
