Wireless Backup Camera Installation Instructions

WARNING

See the Important Safety and Product Information guide in the GPS device product box for product warnings and other important information.

Garmin® strongly recommends having an experienced installer with the proper knowledge of electrical systems install the device. Incorrectly wiring the power cable can result in damage to the vehicle or the battery and can cause bodily injury.

When connecting the power cable, do not remove the in-line fuse holder. To prevent the possibility of injury or product damage caused by fire or overheating, the appropriate fuse must be in place as indicated in the product specifications. In addition, connecting the power cable without the appropriate fuse in place will void the product warranty.

CAUTION

Always wear safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding.

NOTICE

When drilling or cutting, always check what is on the opposite side of the surface.

• Installing the camera higher on the back of the vehicle provides a better viewing angle.

• The included bracket can be clipped onto a license plate or other similar surface, or it can be fastened to the back of the vehicle using the included self-tapping, panhead screws.

Transmitter Location and Wiring Considerations

NOTICE

The transmitter is not intended to be held or worn on your body while it is in use.

When selecting a location to install the wireless transmitter, observe these considerations.

• You should test a proposed installation location before you permanently install the transmitter.

• Some vehicles do not provide constant minimum voltage to the reverse lamps. You should use an automotive relay when connecting the transmitter and camera to a power source that does not provide constant voltage.

• Although the transmitter can transmit the video signal approximately 13.5 m (45 ft.), the location of the transmitter can affect this range.

◦ The closer you install the transmitter to the receiver, the

more reliable the signal.

◦ The signal transmits from the flat front and back surfaces

of the transmitter. The transmitter provides the best

signal when either flat surface points toward the receiver.

These installation instructions do not apply to a specific vehicle type, and are meant as a guide when installing this product on your vehicle. For questions specific to your vehicle, you should contact the vehicle manufacturer.

Item Description

Camera mounting bracket

Tools Needed

• Drill and 0.36 in. (9.09 mm, or size T) drill bit

• #2 Phillips screwdriver

• Screws, bolts, or cable ties (to secure the transmitter)

• Solderless wire-splice connector or solder and heat-shrink tubing

• RV sealant (optional)

Camera Mounting Considerations

When selecting a location to mount the camera, observe these considerations.

• You should test a mounting location before you permanently mount the camera.

◦ Dense metal or appliances Á in the path of the transmitter

greatly reduce the transmission distance.

◦ The fewer solid objects that exist between the path of the

transmitter and the device, the more reliable the signal.

• If the distance between the camera and the transmitter exceeds the length of the included cable, additional extension cables can be used. A 15 m (50 ft.) extension cable can be purchased, and more than one extension cable can be installed. See your Garmin dealer or go to www.garmin.com for more information.

• The fuse holder located near the transmitter is not waterproof. Installing the fuse holder in a location that is exposed to the elements is not recommended.

• The connector between the camera and the transmitter is not waterproof. If you make this connection in a location exposed to the elements, you must make sure that the connection is waterproof.

• If you are installing the camera on a boat trailer or other location that may be exposed to water, you must waterproof all wiring connections and the fuse holder in the transmitter cable.

Testing the Camera and Transmitter Location

Temporarily secure the camera in the preferred mounting

location. Temporarily place the transmitter in the preferred installation

location, and connect it to power and to the camera.

2 Installation Instructions

TIP: If you do not want to splice into the wiring of your vehicle for this test, you can connect the transmitter and camera to a 12 Vdc battery.

Test the transmitter for correct operation by applying power

to the PND device using the wireless camera PND mount. If you do not see video on the device at the preferred

installation location, move the transmitter to another location and test it again.

Repeat steps 2–3 until the transmitter operates correctly.

Test the camera view by observing the video on the device.

If the camera does not provide the optimal view for your

vehicle, move it to another location and test it again. Repeat steps 5–6 until the camera mounting location

provides the optimal view for your vehicle. TIP: Make note of which direction is up when you are testing

the camera view to ensure correct permanent installation.

Mounting the Camera

Before you permanently mount the camera, you should test the mounting location for the optimal view for your vehicle (Testing

the Camera and Transmitter Location, page 2).

If you have already connected the camera to the bracket, you must first disassemble it.

Place the bracket À in the mounting location.

Apply RV sealant around the cable where it enters the

vehicle (optional).

Installing the Transmitter

Before you permanently install the transmitter, you must test the installation location for correct operation (Testing the Camera

and Transmitter Location, page 2).

Secure the transmitter to the installation location using

hardware appropriate for the location, such as screws, bolts, or cable ties.

The fuse holder located near the transmitter is not waterproof. Installing the fuse holder in a location that is exposed to the elements is not recommended.

Connect the camera and transmitter cables.

The connector between the camera and the transmitter is not waterproof. If you make this connection in a location exposed to the elements, you must make sure that the connection is waterproof.

Connect the power cable À from the transmitter to a 12–

24 VDC power source, preferably a reverse lamp Á, using a solderless wire-splice connector (not included).

Select an option:

• If you are mounting the bracket directly on the surface of your vehicle, mark the locations of the two holes on the bracket Á.

• If you are installing the bracket on a license plate, remove one of the license plate screws and clip the bracket in place so the hole on the bracket Â lines up with the hole on the license plate.

Secure the bracket to the vehicle using either the included

self-tapping screws Ã or the license-plate screw you removed in step 2 Ä.

Place the camera in the bracket, and determine the best

place for the camera cable Å to enter the vehicle. Using an appropriate drill bit, drill a hole for the camera cable

to enter the vehicle. Feed the camera cable through the hole and route it to the

transmitter location. 15 m (50 ft.) extension cables can be purchased separately,

if needed. Secure the camera in the bracket using the included hex

bolts Æ. Adjust the angle of the camera and tighten the hex bolts

using the included hex key.

NOTE: Connecting the transmitter to an always-on 12-24 VDC source (such as a running lamp) instead of a reverse lamp requires you to manually switch power to the transmitter. The transmitter may drain your vehicle battery if it is left on.

If you did not use a solderless wire-splice connector, solder

and heat-shrink the electrical connections to protect them from the elements.

Using the Camera

The camera shows video on the device in different ways, depending on how you connected the power to the transmitter.

Select an option to show video:

• If you connected the transmitter to a reverse lamp (recommended), place the vehicle into reverse. The device automatically shows video from the backup camera.

• If you connected the transmitter to a running lamp or other steady 12 VDC source, select the camera icon on the device to show video from the backup camera.

Select an option to resume normal device operation:

• If you connected the transmitter to a reverse lamp (recommended), take the vehicle out of reverse. The device automatically resumes normal operation.

• If you connected the transmitter to a running lamp or other steady 12 VDC source, select the camera icon on the device to resume normal operation.

Aligning the Guidance Lines

Guidance lines provide a visual representation of the vehicle's path when in reverse. For best reference, they should be aligned to reflect the outside edges of the vehicle.

Position the vehicle with one side closely aligned to a curb,

driveway, or parking stall lines.

Installation Instructions 3

You may want to position the vehicle in the center of a parking stall, and then pull forward into the next stall. This allows you to use the parking stall lines in the rear of the vehicle as reference points for alignment.

The curb, driveway, or parking stall lines should be clearly visible on the device.

From the camera view, select > Adjust.

Use the arrows in the corners of the screen to move the

guidance lines to match the angle and position of the curb, driveway, or parking stall lines.

The guidance lines should appear directly on top of your reference points.

Use the arrows in the center of the screen to move the

guidance lines up or down. The red section of the guidance lines should be aligned with

the rear of your vehicle. If necessary, reposition the vehicle with the other side closely

aligned to a curb, driveway, or parking stall lines, and repeat the alignment process.

You should attempt to keep the guidance lines symmetrical, even if your vehicle is not in perfect alignment with the curb, driveway, or parking stall lines.

Select when alignment is complete.

Showing or Hiding Guidance Lines

Select .

Select an option:

• To show the guidance lines on the screen, select Show Lines.

• To hide the guidance lines on the screen, select Hide Lines.

Restoring Alignment

You can reset the guidance lines to their default settings.
