in 2 or 3, make the connection as illustrated.
Please be sure to reconnect the cable as shown 2 below
to install this unit to the Volkswagen vehicles etc.

• 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.
