• In Europe, call +44 (0) 870 850 1241. Software Update You may need to update the chartplotter software after installation. For the instructions on how to update the software, see the owner's manual at garmin.com/manuals/gpsmap7x3-9x3-12x3-16x3/. 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. -
Page 5: Bail Mounting The Device
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. - Page 6 8 After 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 and GPSMAP 16x3 models have six mounting holes. GPSMAP 9x3 and GPSMAP 7x3 models have four mounting holes.

The pieces of the foam gasket have adhesive on the back. Make sure you remove the protective liner before installing them on the device.
- Page 8 On GPSMAP 7x3, GPSMAP 9x3, and GPSMAP 12x3 devices, the raised portion of the nut plate should fit into the smaller hole. On GPSMAP 16x3 devices, the raised portion of the nut plate should fit into the larger hole. 8 Secure the nut plates to the mounting surface by fastening the pan head machine screws through the holes with the raised portion of the nut plate.

• The CVBS IN port uses a BNC connector. You can use a BNC to RCA adapter to connect a composite-video source with RCA connectors to the CVBS IN port. • Video is shared across the Garmin Marine Network, but it is not shared across the NMEA 2000 network. - Page 18 The Garmin GPSMAP HDMI accessory cable is 4.5 m (15 ft.) long. If you need a longer cable, you should use an active HDMI cable only. You need an HDMI coupler to connect the two HDMI cables.
