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.

When selecting a mounting location, you should observe these considerations.

•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.

•The location must not be a flat, horizontal surface. The location should be in a vertical angle.

The location and viewing angle should be tested before you install the device. High viewing angles from above and below the display may result in a poor image.

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 cracking in the gel-coat layer when the screws are tightened.

You can use the bracket to bail mount the device on a flat surface.

1Using the bail-mount bracket as a template, mark the pilot holes .

2 Using a 3 mm (1/8 in.) drill bit, drill the pilot holes.

3Secure the bail-mount bracket to the surface using the included washers and wood screws .

4 Install the bail-mount knobs on the sides of the device.

5Place the device in the bail-mount bracket, and tighten the bail-mount knobs.

6Install the trim caps by snapping them in place around the edges of the device.

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.

Use only the included hardware when mounting this device. Using mounting hardware not provided with the device may damage the device.

To avoid potential damage to the powder coating, use only the included screws to mount the device. Using screws other than the ones included will void your warranty.

Do not use the device as a template when drilling the mounting holes because this may damage the glass display and void the warranty. You must only use the included template to correctly drill the mounting holes.

If you will not have access to the back of the device and the microSD memory card slots after installations, you should install the microSD memory card prior to installation.

The included template and hardware can be used to flush mount the device in your dashboard. There are three options for hardware based on the mounting surface material.

•You can drill pilot holes and use the included wood screws.

•You can drill holes and use the included nut plates and machine screws. The nut plates can add stability to a thinner surface.

•You can punch and tap holes, and use the included machine screws.

1Trim the template, and make sure it fits in the location where you want to mount the device.

2 Secure the template to the mounting location.

3Using a drill bit according to the list below, drill one or more of the holes inside the corners of the solid line on the template to prepare the mounting surface for cutting.

Device	Drill bit size
GPSMAP 7x3	6.5 mm (1/4 in.)
GPSMAP 9x3	7.4 mm (5/16 in.)
GPSMAP 12x3	13.5 mm (9/16 in.)

4Using a jigsaw or a rotary tool, cut the mounting surface along the inside line on the template.

5 Place the device in the cutout to test the fit.

6If necessary, use a file and sandpaper to refine the size of the cutout.

7 If necessary, remove the trim caps.

NOTICE

Use a plastic pry tool when possible. Using a metal pry tool, such as a screwdriver, can damage the trim caps and the device.

8After the device fits correctly in the cutout, ensure the mounting holes on the device line up with the hole locations on the template.

NOTE: GPSMAP 12x3 models have six mounting holes. GPSMAP 9x3 and GPSMAP 7x3 models have four mounting holes.

9If the mounting holes on the device do not line up, mark the new hole locations.

10Based on your mounting method, drill or punch and tap the outer holes on the template:

•For the included wood screws, drill 3.5 mm (9/64 in.) holes, and skip to step 18.

•For the included nut plate and machine screws, drill 3.5 mm (9/64 in.) holes in the outer hole locations.

•For the included machine screws without the nut plate, punch and tap M3 holes, and skip to step 18.

11If you are using a nut plate, starting in one corner of the template, place a nut plate over the hole drilled in the previous step.

The other hole on the nut plate should line up with the inner hole on the template.

12If the inner hole on the nut plate does not line up with the inner hole on the template, mark the new hole location.

13If you are using a nut plate, using a 3 mm (1/8 in.) drill bit, drill a hole in the inner hole location.

14Repeat to verify placement of the remaining nut plates and holes on the template.

15Remove the template from the mounting surface.

16Starting in one corner of the mounting location, place a nut plate on the back of the mounting surface, lining up the holes.

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

17Secure the nut plates to the mounting surface by fastening the pan head machine screws through the inner holes.

18Install the foam gasket on the back of the device.

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

19If you will not have access to the back of the device after you mount it, connect all necessary cables and install microSD cards in the back of the device before placing it into the cutout.

NOTICE

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

20Apply marine sealant between the mounting surface and the device to properly seal and prevent leakage behind the dashboard.

21If you will have access to the back of the device, apply marine sealant around the cutout.

22Place the device into the cutout.

23Secure the device to the mounting surface using the flat head machine screws or the included wood screws.

24Wipe away all excess marine sealant.

25Install the trim caps by snapping them in place around the edges of the device.

Connection Considerations

After connecting the cables to the device, tighten the locking rings to secure each cable.
