• 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.
