Connecting the System
Before installing this product
• This product is for vehicles with a 12-volt battery and negative earthing. Check the bat-
tery voltage of your vehicle before installation.
To prevent damage
When replacing the fuse, be sure to only use a fuse of the rating prescribed on this
product.
• When disconnecting a connector, pull the connector itself. Do not pull the lead, as you
may pull it out of the connector.
• This product cannot be installed in a vehicle that does not have an ACC (accessory)
position on the ignition switch.
• To avoid short-circuiting, cover the disconnected lead with insulating tape. It is especial-
ly important to insulate all unused speaker leads, which if left uncovered may cause a
short circuit.
• Attach the connectors of the same colour to the corresponding coloured port, i.e., blue
connector to the blue port, black to black, etc.
• Refer to the owner’s manual for details on connecting the power amp and other units,
then make connections accordingly.
• Since a unique BPTL circuit is employed, do not directly earth the ≠ side of the speaker
lead or connect the ≠ sides of the speaker leads together. Be sure to connect the ≠ side
of the speaker lead to the ≠ side of the speaker lead on this navigation system.
• If the RCA pin jack on this product will not be used, do not remove the caps attached to
the end of the connector.
• Never connect speakers with an output rating of less than 50 W channel or impedance
outside of the 4 ohms to 8 ohms specifications to your navigation system. Connecting
speakers with output and/or impedance values other than those noted here may result in
the speakers catching fire, emitting smoke, or becoming damaged.
• When the “ANT CTRL” mode is set to “Tuner”, the vehicle’s aerial can be stowed or
turned off by following the instructions below.
– Change the source from radio (MW/LW or FM) to another source
– Turn the source off
– Turn off the ignition switch (ACC OFF)
• If the “ANT CTRL” mode is set to “Power”, the vehicle’s aerial can be stowed or turned
off only when the ignition switch is turned off (ACC OFF).
