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. June 2006 Part Number 190-00495-13 Rev. A Printed in Taiwan Getting Started RF Remote GPS antenna and metal plate GVN 52 Screws (4) Hook and loop fasteners (2) Wiring harness 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 Composite video mode switch SD card Yellow RCA Composite Video Audio L White RCA Red RCA Audio R Audio Mute GVN 52 2A 2A Black (GND) To vehicle chassis Red (ACC) To ignition (12 V) Yellow (BATT) To battery (12 V) WARNING 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. GPS antenna Car fuse box Best (roof of vehicle) Good (inside car on dashboard) Installing the GPS antenna Better (trunk of vehicle) 2. 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. Peel the backing off of the adhesive on the bottom of the metal plate. To mount the GPS antenna inside your vehicle: 1. Clean your dashboard or other surface. 3. Place the GPS antenna on top of the metal plate. CAUTION Car fuse box (main fuse) 4. Ignition key switch 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. 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.
