Accessories/ Installation Procedure
Accessories 1..1 2..2 3..1 4..1
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 chasis 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 connectionsystem, 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 vehicles 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 units 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 or less.

When the connection is made as in 3 above, the units power will not be linked to the ignition key. For that reason, always make sure to turn off the units power when the ignition is turned off. To link the units 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

Metal mounting strap (commercially available) Firewall or metal support
Screwing the Faceplate on the Unit
If you want to fasten the faceplate to the main unit so that it does not fall off, screw in the provided screws in the holes shown below.

Bend the tabs of the mounting sleeve with a screwdriver or similar utensil and attach it in place. Self-tapping screw (commercially available) Screw (M4X8) (commercially available)
Never insert the screw in any other screw hole than the one specified. If you screw them in another hole, it will contact and may cause damage to the mechanical parts inside the unit.
Make sure that the unit is installed securely in place. If the unit is unstable, it may malfunction (for example, the sound may skip).

Removing the Unit

Removing the hard rubber frame 1 Engage the catch pins on the removal tool and
remove the two locks on the upper level. Upper the frame and pull it forward as shown in the figure.
Removing the Unit 1 Refer to the section <Removing the hard rubber 2 3
