Installation Procedure

1. To prevent short circuits, remove the key from the ignition and disconnect the ⊖ terminal of the battery.
2. Make the proper input and output wire connections for each unit.
3. Connect the wire on the wiring harness.
4. Take Connector B on the wiring harness and connect it to the speaker connector in your vehicle.
5. Take Connector A on the wiring harness and connect it to the external power connector on your vehicle.
6. Connect the wiring harness connector to the unit.
7. Install the unit in your car.
8. Reconnect the terminal of the battery.
9. Press the reset button.

!

• If the power is not turned ON (or it is ON, but will be OFF immediately), the speaker wire may have a short-circuit or touched the chassis of the vehicle and the protection function may have been activated. Therefore, the speaker wire should be checked.
• If your car is not prepared for this special connection-system, consult your Kenwood dealer.
• Only use antenna conversion adapters (ISO-JASO) when the antenna cord has an ISO plug.

• Make sure that all wire connections are securely made by inserting jacks until they lock completely.

• If your vehicle's ignition does not have an ACC position, or if the ignition wire is connected to a power source with constant voltage such as a battery wire, the power will not be linked with the ignition (i.e., it will not turn on and off along with the ignition). If you want to link the unit's power with the ignition, connect the ignition wire to a power source that can be turned on and off with the ignition key.

• If the fuse blows, first make sure that the wires have not caused a short circuit, then replace the old fuse with one with the same rating.
  • Insulate unconnected wires with vinyl tape or other similar material. To prevent short circuits, also do not remove the caps on the ends of the unconnected wires or the terminals.
• Connect the speaker wires correctly to the terminals to which they correspond. The unit may receive damage or fail to work if you share the wires and/or ground them to any metal part in the car.
  • After the unit is installed, check whether the brake lamps, indicators, wipers, etc. on the car are working properly.
• If the console has a lid, make sure to install the unit so that the faceplate does not hit the lid when closing and opening.
• Mount the unit so that the mounting angle is 30^irc or less.

▲WARNING

Connecting the ISO Connector

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.

The default connection for the wiring harness is described in 1 below. If the ISO connector pins are set as described 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.

1(Default setting) The A-7 pin (red) of the vehicle's ISO connector is linked with the ignition, and the A-4 pin (yellow) is connected to the constant power supply.

3 The A-4 pin (yellow) of the vehicle's ISO connector is not connected to anything, while the A-7 pin (red) is connected to the constant power supply (or both the A-7 (red) and A-4 (yellow) pins are connected to the constant power supply).

- 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.

Installation
