Mounting the Components

Mounting Considerations

NOTICE

This device should be mounted in a location that is not exposed to extreme temperatures or conditions. The temperature range for this device is listed in the product specifications. Extended exposure to temperatures exceeding the specified temperature range, in storage or operating conditions, may cause device failure. Extreme-temperature-induced damage and related consequences are not covered by the warranty.

Using the included hardware and template, you can mount the device using one of two methods. You can use the included bracket and hardware to bail mount the device, or you can use the included template and hardware to flush mount the device in the dashboard. If you want to mount the device using an alternative method where it appears flat with the front of the dashboard, you must purchase a flat-mount kit (sold separately, with professional installation recommended) from your Garmin dealer.

When selecting a mounting location, observe these considerations.

NOTE: Not all mounting methods are available for all device models. See the specific mounting-type section for more details about your model.

• The location should provide optimal viewing as you operate your boat.

• The location should allow for easy access to all device interfaces, such as the keypad, touchscreen, and card reader, if applicable.

• The location must be strong enough to support the weight of the device and protect it from excessive vibration or shock.

• To avoid interference with a magnetic compass, the device should not be installed closer to a compass than the compass-safe distance value listed in the product specifications.

• The location must allow room for the routing and connection of all cables.

Bail Mounting the Device

NOTICE

If you are mounting the bracket on fiberglass with screws, it is recommended to use a countersink bit to drill a clearance counterbore through only the top gel-coat layer. This will help to avoid any cracking in the gel-coat layer when the screws are tightened.

The bail-mounting hardware (screws and washers or nuts, washers, and bolts) is not included. The holes on the bail-mount bracket are 5/16 in. (7.9 mm) in diameter. Before you can bail mount the device, you must choose mounting hardware that fits the holes in the bail-mount bracket and securely attaches it to your specific mounting surface. The size of the pilot hole required depends on the mounting hardware you choose.

You can bail mount only the eight-inch and 12-inch models. Due to the size of the 15-inch models, you must install them using the flush-mount or flat-mount method.

Using the included bail-mount bracket À as a template, mark

the location of the four pilot holes Á.

Using a drill bit appropriate for your mounting hardware, drill

the pilot holes. Secure the bail-mount bracket to the surface using your

mounting hardware Â. Install the bail-mount knobs Ã on the sides of the device.

Place the device in the bail-mount bracket, and tighten the

bail-mount knobs.

Securing the Device

You can lock the device to the structure of your boat for added security (optional).

Bail-mount the device (Bail Mounting the Device).

Using a coated braided-steel cable (not included) and a lock

(not included), secure the back of the case À to the structure of the boat.

Using a 13 mm (½ in.) drill bit, drill one or more of the holes

inside the corners of the solid line on the template to prepare the mounting surface for cutting.

Using a jigsaw, cut the mounting surface along the inside of

the solid line indicated on the template. Place the device in the cutout to test the fit.

If necessary, use a file and sandpaper to refine the size of

the cutout. After the device fits correctly in the cutout, ensure the

mounting holes on the device line up with the larger 7.2 mm (9/32 in.) holes on the template.

If the mounting holes on the device do not line up, mark the

new hole locations. Using a 7.2 mm (9/32 in.) drill bit, drill the larger holes.

Starting in one corner of the template, place a nut plate

over the larger hole Á drilled in step 9.

The smaller 3.5 mm (9/64 in.) hole Â on the nut plate should line up with the smaller hole on the template.

If the smaller 3.5 mm (9/64 in.) hole on the nut plate does not

line up with the smaller hole on the template, mark the new hole location.

Repeat steps 10–11 to verify placement of the remaining nut

plates and holes on the template. Using a 3.5 mm (9/64 in.) drill bit, drill the smaller holes.

Remove the template from the mounting surface.

Starting in one corner of the mounting location, place a nut

plate Ã on the back of the mounting surface, lining up the large and small holes.

The raised portion of the nut plate should fit into the larger hole.

Flush Mounting the Device

NOTICE

Be careful when cutting the hole to flush mount the device. There is only a small amount of clearance between the case and the mounting holes, and cutting the hole too large could compromise the stability of the device after it is mounted.

The included template and hardware can be used to flush mount the device in your dashboard. To mount the device so the screen is flat with the dashboard, you must purchase a flatmount kit from your Garmin dealer.

Trim the template and make sure it fits in the location where

you want to mount the device. Remove the protective liner from the back of the template

and adhere it to the location where you want to mount the device.

Secure the nut plate to the mounting surface by fastening an

included M3 screw Ä through the smaller 3.5 mm (9/64 in.) hole.

Repeat steps 15–16 to secure the remaining nut plates to the

mounting surface. Install the rubber gasket Å on the back of the device.

The pieces of the rubber gasket have adhesive on the back. Make sure you remove the protective liner before installing them on the device.

If you will not have access to the back of the device after you

mount it, connect all necessary cables to the device before placing it into the cutout.

NOTE: To prevent corrosion of the metal contacts, cover unused connectors with the attached weather caps.

Place the device into the cutout.

Secure the device to the mounting surface using the included

M4 screws Æ. Insert the included plugs over each of the M4 screw heads.

Install the decorative bezel by snapping it in place around the

edges of the device.

Card Reader Mounting Considerations

NOTICE

The card reader can be flush mounted in the dashboard using the included hardware. When selecting a mounting location, observe these considerations.

• The card reader should be mounted in an accessible location. You must be able to access the card reader when necessary to insert and remove memory cards containing additional mapping and device updates, and to transfer user data.

• To avoid interference with a magnetic compass, the device should not be installed closer to a compass than the compass-safe distance value listed in the product specifications.

• The location must allow room for the routing and connection of the cables.

Mounting the Card Reader

NOTICE

The included template and hardware can be used to flush mount the device at the selected location.

Trim the flush-mount template and make sure it fits in the

location where you want to mount the device. Remove the protective liner from the back of the template

and adhere it to the location where you want to mount the device.

Using a 6 mm (¼ in.) drill bit, drill one or more of the holes

inside the corners of the solid line on the template to prepare the mounting surface for cutting.

Using a jigsaw, cut the mounting surface along the inside of

the solid line indicated on the template. Place the device in the cutout to test the fit.

If necessary, use a file and sandpaper to refine the size of

the cutout. After the device À fits correctly in the cutout, make sure the

mounting holes on the device line up with the pilot holes on the template.

If the mounting holes on the device do not line up, mark the

new pilot-hole locations. Using a center punch, indent the pilot holes and drill the

clearance counterbore through the gel-coat layer as advised in the notice.

Remove the template from the mounting surface.

If you will not have access to the back of the device after you

mount it, connect all necessary cables to the device before placing it into the cutout.

Place the device into the cutout.

Secure the device to the mounting surface using the included

screws Â. Install the decorative bezel by snapping it in place around the

edges of the device.

Antenna Mounting Considerations

You can mount the antenna on a flat surface, install it under fiberglass, or attach it to a standard 1 in. OD, 14 threads per inch, pipe-threaded pole (not included). You can route the cable outside of the pole or through the pole. For best performance, consider these guidelines when selecting the antenna mounting location.

• To ensure the best reception, the antenna should be mounted in a location that has a clear, unobstructed view of the sky in all directions À.

• The antenna should not be mounted where it is shaded by the superstructure of the boat Á, a radome antenna, or the mast.

• The antenna should not be mounted near the engine or other sources of Electromagnetic Interference (EMI) Â.

• If a radar is present, the antenna should be mounted above the path of the radar Ã. If necessary, the antenna may be mounted below the path of the radar Ä.

• The antenna should not be mounted directly in the path of the radar Å.

• The antenna should be mounted at least 1 m (3 ft.) away from (preferably above) the path of a radar beam or a VHF radio antenna Æ.

Testing the Mounting Location

Temporarily secure the antenna in the preferred mounting

location and test it for correct operation. If you experience interference with other electronics, move

the antenna to a different location, and test it again. Repeat steps 1–2 until you observe full or acceptable signal

strength. Permanently mount the antenna.

Surface Mounting the Antenna

NOTICE

Stainless-steel screws may bind when screwed into fiberglass and overtightened. Garmin recommends applying an anti-seize lubricant to the screws before installing them.

Set the surface-mount bracket aside.

Do not drill through the bracket. Drill the three 3.2 mm (1/8 in.) pilot holes.

Use a 25 mm (1 in.) hole saw to cut the cable hole in the

center. Place the seal pad Á on the bottom of the surface-mount

bracket, aligning the screw holes. Use the included M4 screws to secure the surface-mount

bracket to the mounting surface. Route the cable Â through the 25 mm (1 in.) hole and

connect it to the antenna. Verify the large gasket Ã is in place on the bottom of the

antenna, place the antenna on the surface-mount bracket, and twist it clockwise to lock it in place.

Secure the antenna to the mounting bracket with the

included M3 set screw Ä. Route the cable away from sources of electronic

interference.

Mounting the Antenna with the Cable Routed Outside the Pole

Before you permanently mount the antenna, you must test the mounting location for correct operation (Antenna Mounting

Considerations).

Route the cable through the pole-mount adapter À, and

place the cable in the vertical slot Á along the base of the pole-mount adapter.

Before you permanently mount the antenna, you must test the mounting location for correct operation (Antenna Mounting

Considerations).

Using the surface-mount bracket À as your mounting

template, mark the three pilot-hole locations and trace the cable-hole in the center of the bracket.

Screw the pole-mount adapter onto a standard 1 in. OD, 14

threads per inch, pipe-threaded pole (not included). Do not overtighten the adapter on the pole. Connect the cable to the antenna.

Place the antenna on the pole-mount adapter and twist it

clockwise to lock it in place.

Secure the antenna to the adapter with the included M3 set

screw Â. With the antenna installed on the pole mount, fill the

remaining gap in the vertical cable slot with a marine sealant (optional).

Attach the pole to the boat if it is not already attached.

Route the cable away from sources of electronic

interference.

Mounting the Antenna with the Cable Routed Through the Pole

Before you permanently mount the antenna, you must test the mounting location for correct operation (Antenna Mounting

Considerations).

Position a standard 1 in. OD, 14 threads per inch, pipe-

threaded pole (not included) in the selected location, and mark the approximate center of the pole.

Drill a hole using a 19 mm (3/4 in.) drill bit for the cable to

pass through. Fasten the pole to the boat.

Thread the pole-mount adapter onto the pole.

Do not overtighten the adapter. Route the cable through the pole and connect it to the

antenna. Place the antenna on the pole-mount adapter and twist it

clockwise to lock it in place. Secure the antenna to the adapter with the included M3 set

screw À.

Place the antenna in the under-deck mounting bracket.

Adhere the under-deck mounting bracket to the mounting

surface. Secure the under-deck mounting bracket to the mounting

surface with screws. Connect the cable to the antenna Â.

Route the cable away from sources of electronic

interference.

Cable and Connection Considerations

NOTICE

A blue rubber seal is included for each DVI port on the device. This seal must be installed between each DVI port and DVIcable connector to avoid damage to the connectors.

With the antenna installed on the pole mount, fill the vertical

cable slot Á with a marine sealant (optional). Route the cable away from sources of electronic

interference.

Mounting the Antenna Under the Deck

NOTICE

Before attaching the under-deck mounting bracket to the surface, verify the included screws will not penetrate the surface. If the included screws are too long, you must purchase surface-appropriate screws to complete the installation.

Before you permanently mount the antenna, you must test the mounting location for correct operation (Antenna Mounting

Considerations).

Because the antenna cannot acquire signals through metal, it must be mounted under a fiberglass surface only.

Place the adhesive pads À on the under-deck mounting

bracket Á.

• For easer cable routing, the power, NMEA® 0183, and Garmin Marine Network cables are packaged without the locking rings installed. You should route the cables before you install the locking rings.

• After connecting a locking ring to a cable, make sure the ring is securely connected and the o-ring is in place so the power or data connection remains secure.

• The device should be connected to the same power source as the card reader. If this is not possible, the devices must be connected to the same ground.

Station Connection Considerations

This device can be set up in conjunction with other compatible Garmin devices to work together as a station. When planning stations on your boat, observe these considerations.

• Devices earlier than the GPSMAP 8000 series and GPSMAP 8500 series cannot be used in a station.

• Although it is not necessary, it is recommended that you install all of the devices you plan to use in one station near each other.

• No special connections are necessary to create a station, as long as all of the devices are connected to the Garmin Marine Network (Garmin Marine Network Considerations).

• Stations are created and modified using the device software. See the owner's manual provided with the device for more information.
