KNA-G520

GPS NAVIGATION SYSTEM

INSTALLATION MANUAL

B54-4501-08

Warning

Failure to avoid the following potentially hazardous situations could result in serious injury or re. Do not attempt to install or service the KNA-G520 by yourself. Installing or servicing the unit without training and experience in electronic equipment and automotive accessories may be dangerous and could expose you to the risk of electric shock or other hazards. When extending ignition, battery, or ground wires, use automotive-grade wires or other wires with AWG 18 (0.75 mm2 gauge) or greater to prevent wire deterioration and damage to the wire coating. If the unit starts to emit smoke or strange smells, turn off the power immediately and consult your Kenwood dealer. Keep small articles (like screws or batteries) out of the reach of children. If any such object is accidentally swallowed, consult a doctor immediately.

Caution

Failure to avoid the following potentially hazardous situations may result in injury or property damage. Make sure to ground the unit to the chassis of your vehicle. Secure all wiring with cable clamps or electrical tape. Insulate unconnected wires; do not allow any bare wiring to remain exposed. Do not let unconnected wires or terminals touch metal on the vehicle or anything else that can conduct electricity. Do not open the top or bottom covers of the unit. The KNA-G520 is not waterproof.

Whats Included

GPS antenna

main unit

screws (4)

wiring harness

hook and loop fasteners (2)
Use the screws or the hook and loop fasteners (similar to Velcro) provided to mount the main unit in the vehicle. Select a location that allows you to access the units SD card slot. Be sure to place the unit horizontally (at) and secure it completely for best performance.

Installing the main unit

Do not install the unit where it will be exposed to direct sunlight, excessive heat or humidity, dust, spills, or liquids. Use only the screws provided. If you use the wrong screws, you could damage the unit. Check for cables or other parts underneath the oor mat before cutting the oor mat.
Installing the GPS antenna
Do not paint the antenna. This will impair or disable signal reception. Remove any object or accumulated snow, etc., from the top of the antenna. It will reduce reception strength. Do not pull the cord when removing the antenna or adjusting its position. This can cause a short or snap the wires.
The GPS antenna can be installed either inside or outside the vehicle. It should be placed horizontally for best GPS reception. The GPS antenna must have a clear view of the sky. If you install the antenna inside the vehicle, place it close to a window; GPS signals can pass through glass but not through metal. Refer to the image on the next page for recommended places to install the antenna. Place the GPS antenna on a metallic surface, such as the roof of your vehicle, for best reception. For information on installing the optional FM trafc receiver (such as the GTM 10), refer to the Installation Guide included with the trafc receiver.
Installing optional accessories Setting Up Dead Reckoning
Dead Reckoning (DR) allows the navigation system to continue to provide navigation guidance even if it loses GPS reception. After you connect the pink wire and start the navigation sytem, you must set up Dead Reckoning before it will work correctly. From the Menu page of the navigation system, touch Settings > Navigation > Dead Reckoning Setup > Settings. Odometer Wave Typeselect Square Wave or Sine Wave. Determine the proper setting by contacting the vehicle manufacturer or by using an oscilloscope. Square Wave is the most common type. Reverse Light Polarityselect High or Low. Contact the vehicle manufacturer for polarity or check with a voltmeter. Set to High (most common) if a positive, high voltage is detected when the reverse lights are illuminated. Set to Low if no voltage or low voltage is detected when the reverse lights are illuminated.

CAUTION

If your vehicles ignition does not have an ACC position, connect the ignition wires to a power source that can be turned on and off with the ignition key. If you connect the ignition wire to a power source with a constant voltage supply, as with battery wires, the vehicles battery may die.

Acquiring GPS Signals
The rst time you turn on the KNA-G520, you must wait while the system acquires satellite signals for the rst time. This process could take up to several minutes. Make sure your vehicle is outdoors in an open area away from tall buildings and trees for fastest acquisition. After the system acquires satellites for the rst time, it will acquire satellites quickly each time thereafter.

Changing the Fuses

If you need to replace a fuse on the red or yellow wires, make sure the wires are not touching to prevent a short circuit. Then replace the old fuse with a new 2 Amp fuse.
When replacing a fuse, use only a new fuse with the prescribed rating. Using a fuse with the wrong rating may cause your unit to malfunction. Disconnect the wiring harness before replacing a fuse to prevent short circuits.
