GVN 52
installation instructions
WARNING
Failure to avoid the following potentially hazardous situations could result in serious injury, fire, or death.
• Do not attempt to install or service the GVN 52 unless you are a professional electronics installer. 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.
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 expose the GVN 52 to water or other liquids. The GVN 52 is not waterproof.

Remote control
Before you begin installation, disconnect the negative battery cable. Then follow the steps below to install the GVN 52.
➊
Install the GPS antenna
Install the GPS antenna on the outside of the vehicle on a metal surface or metal plate. The plate or surface must be at least 3.5
inches by 3.5 inches square. The GPS antenna must have a clear view of the sky and must be placed horizontally for best GPS
reception. See the next page for further instructions.
CAUTION
The permanent adhesive on the back of the metal plate is extremely difficult to remove after it is installed.
➋
Connect the wiring harness
Connect each wire to the appropriate signal in the vehicle. Refer to the wiring diagram for more information. Wrap any unused
wires with electrical tape; do not leave any metal exposed.
➌
Install the GVN 52
Use the screws or the hook and loop fasteners provided to mount the GVN 52 in the vehicle. Select a location that allows you to
access the unit’s SD card slot. We recommended installing it under a seat or in another place close to the driver. Do not install the
GVN 52 inside a metal housing or where it might be shielded from you by a metal object. If there are large metal objects between
you and the GVN 52, the remote control may not work.
CAUTION
Do not install the unit where it will be exposed to direct sunlight, excessive heat or humidity, or dust. Use only the screws
provided. If you use the wrong screws, you could damage the unit.
➍
Install optional accessories
You can install an optional XM Smart Antenna (such as the GXM 30) either inside or outside the vehicle. Like the GPS antenna, it
must have a clear view of the sky. If you use an extension cable with the XM antenna, wrap the two connectors with electrical tape.
For information on installing an optional FM traffic receiver (such as the GTM 10), refer to the Installation Guide included with the
traffic receiver.
➎
Test the installation
Reconnect the negative battery cable, and then turn on the audio/video system to ensure that everything is connected and is
functioning properly. Install batteries in the remote. Then test the remote control to ensure that it is working. If the remote control
does not work, you may need to move the GVN 52 to a different location in the vehicle.

Optional accessory:
XM Smart Antenna or
FM traffic receiver
GPS antenna
Do not connect the yellow wire
directly to the vehicle battery.
Doing so may cause the wire
insulation to fail and may pose a
risk of short circuit and electric
shock.
WARNING
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, such as battery
wires, the vehicle’s battery may die.

Installing the GPS antenna
Composite video
mode switch
To mount the GPS antenna inside your vehicle:
1. Clean your dashboard or other surface.
2. Peel the backing off of the adhesive on the bottom of the
metal plate.
3. Press the metal plate down firmly on your dashboard or
other mounting surface. You can bend the metal plate to
conform to a curved surface, if necessary.
4. Place the GPS antenna on top of the metal plate.
Acquiring GPS Signals
The first time you turn on the GVN 52, you must wait while the system acquires satellite signals for the first 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 first 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.
CAUTION
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.
