•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.
