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.
• When flush mounting the device, the location must not be a flat, horizontal surface. The location should be at 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 included bracket to bail mount the device on a flat surface.

1. Using the bail-mount bracket (1) as a template, mark the pilot holes.
   
2. Using a 3.5 mm (9/64 in.) drill bit, drill the pilot holes.
3. Using the included screws (2), secure the bail-mount bracket to the mounting surface.
4. Install the bail-mount knobs (3) on the sides of the device.
5.  Place the device in the bail-mount bracket and tighten the bail-mount knobs.

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. 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. Before cutting or drilling to flush mount the device, be sure the space behind the mounting surface can accommodate the radio.

The included template and hardware can be used to mount the device in your dashboard.

1. Trim the template and make sure it fits in the location where you want to mount the device.
2. Using a 9.5 mm (3 /8 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.
3. Using a jigsaw or rotary tool, cut the mounting surface along the inside of the solid line indicated on the template.
4. Place the device in the cutout to test the fit.
5. If necessary, use a file and sandpaper to refine the size of the cutout.
6. After the device fits correctly in the cutout, ensure the mounting holes on the device line up with the pilot holes on the template.
7. If the mounting holes on the device do not line up, mark the new pilot-hole locations.
8. Using a 3.5 mm (9 /64 in.) drill bit, drill the pilot holes.
9. Remove the template from the mounting surface.
10. 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.
11. If necessary, cover unused connectors with the attached weather caps to prevent corrosion of the metal contacts.
12. Remove the protective liner from the foam gasket.
13. Install the gasket (1) on the back of the device.
14. Place the device in the cutout.
15. Secure the device to the mounting surface using the included screws (2).
16. Install the decorative bezel by snapping it in place around the edges of the device.

Mounting the Microphone Hanger

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 mount the microphone hanger in a convenient location near the radio.

1. Select a mounting location for the microphone within reach of the microphone cable.
2. Using the microphone hanger(1)as a template, mark the pilot holes.
   
3. Drill the mounting holes using a 3 mm (1 /8 in.) drill bit.
4. Secure the microphone hanger to the mounting surface using the included screws (2).

Connection Considerations

Connectors and port locations vary by model.

Connecting to Power

1. Route the power wiring cable to the power source and to the device.
2. Connect the red wire to the positive (+) battery terminal, and connect the black wire to the negative (-) battery terminal.

NMEA 2000 Connections

NOTICE
If you are installing an NMEA 2000 power cable, you must connect it to the boat ignition switch or through another in-line switch. NMEA 2000 devices will drain your battery if the NMEA 2000 power cable is connected to the battery directly.

If you are unfamiliar with NMEA 2000, you should read the “NMEA 2000 Network Fundamentals” chapter of the Technical Reference for NMEA 2000 Products. Go to garmin.com/manuals/nmea_2000.

Connecting to a Remote GPS Antenna
This device includes an internal GPS antenna. If your mounting location does not provide good GPS reception, you may install a remote GPS antenna with a female BNC connector (not included), and connect it to the device.

NOTE:
If you connected this device to an NMEA 2000 with a GPS antenna, you can use that antenna as a GPS source instead of installing a remote GPS antenna.

1. Follow the instructions provided with the external GPS antenna to install it on your boat correctly.
2. Route the GPS antenna cable to the back of the VHF 115/VHF 215/VHF 215 AIS device, away from sources of electrical interference.
3. Connect the GPS antenna cable to the BNC connector on the wiring harness on the VHF 115/VHF 215/VHF 215 AIS device.

Connecting to an External Speaker

You can connect your VHF device to an external marine speaker (not included) to amplify sound at remote locations on the vessel or to communicate with other vessels.

1. If necessary, mount the external marine speaker according to the installation instructions provided with the speaker.
2. Route or extend the wire from the external speaker to the VHF device.
3. Connect the red wire on the data cable to the positive (+) wire from the external speaker. NOTE: Make sure this is the red wire on the data cable. The power harness has a red wire that connects to the power source.
4. Connect the black wire on the data cable to the negative (-) wire from the external speaker. NOTE: Make sure this is the black wire on the data cable. The power harness has a black wire that connects to the power ground.
5. Cover the connections with waterproof tape or heat-shrink tubing.

Connecting to a Hailer Horn or PA Speaker

You can connect a VHF 215 radio to a hailer horn or public address (PA) speaker (not included) to use the microphone or the handset to make announcements. NOTE: The VHF 115 models cannot be connected to a hailer horn. Some VHF models include a foghorn feature as part of the public address system. You can sound the foghorn through a hailer horn or a PA speaker. To use the foghorn you must provide and install a hailer horn (optional) on the deck or tower of your boat.

1. If necessary, mount the hailer horn or PA speaker according to the installation instructions provided with the device. NOTE: To avoid feedback, you should mount the hailer horn or PA speaker at least 3 m (10 ft) away from, and facing away from, the microphone or handset.
2. Route or extend the wire from the hailer horn or PA speaker to the radio.
3. Connect the white wire on the data cable to the positive (+) wire from the hailer horn or PA speaker.
4. Connect the green wire on the data cable to the negative (-) wire from the hailer horn or PA speaker.
5. Cover the connections with waterproof tape or heat-shrink tubing.
