Bail Mounting the Chartplotter Use the included bracket to bail mount the GPSMAP 700 series chartplotter. You can route cables from under the mounting surface through the included bail-mount bracket, though it is not necessary. See page 3 for instructions on installing the bail-mount bracket without routing cables through the bracket. Hardware (included): • Bail-mount bracket • Cable-organization bracket • Bail-mount template • Four 35 mm M 4.2 × 1.4 screws (to secure the bail-mount bracket ) • Two 20 mm M 3.5 × 1.3 screws (to secure the cable-organization bracket) Tools required (not included): • Jigsaw • Drill and drill bits-1 1/4 in. (32 mm), and 1/8 in. (3 mm) • Number 2 Phillips screwdriver To install the bail-mount bracket with the cables routed through the bracket: 1. Using the included bail-mount bracket template, determine the best place to install the bracket. Be sure to leave adequate clearance behind the chartplotter for the wiring. NOTE: To avoid interference, mount the GPSMAP 700 series chartplotter at least 32 in. (813 mm) from a magnetic compass. 2. The bail-mount bracket template has adhesive on the back. Remove the protective liner and apply the template to the location at which you want to install the bail-mount bracket. GPSMAP 700 series chartplotter 3. Use a 1 1/4 in. (32 mm) drill bit to drill the pass-through hole in the center of the template. 4. Use a use a 1/8 in. (3 mm) drill bit to drill the six pilot holes marked on the bailmount template. Bail-mount bracket Note: If you are mounting the chartplotter in fiberglass, it is recommended to use a countersink bit to drill a clearance-counter bore through only the top gel-coat layer. This will help to avoid any cracking in the gel-coat layer when the screws are tightened. 5. Remove the bail-mount bracket template from the mounting surface. 6. Route the cables pertinent to your installation through the hole you drilled in step 3, from under the mounting surface. If you plan to use all four cables, route them in the following order to ensure that they will all fit correctly: Cable-organization bracket • Radar cable • Power/data wiring cable • GA 30 GPS antenna cable • NMEA 2000 cable Bail-Mounting the GPSMAP 700 Series Chartplotter NOTE: Do not install the locking ring (page 4) on the power/data or radar cable until after you route it through the mounting surface. 7. Place the cable-organization bracket around the cables and into the 1 1/4 in. (32 mm) hole you drilled in step 3. 8. Use the two included 20 mm M 3.5 × 1.3 screws to secure the cable-organization bracket to the mounting surface. Note: Stainless-steel screws may bind when screwed into fiberglass and overtightened. Garmin recommends applying an anti-galling, stainless anti-seize lubricant to the screw before using. 9. Extend 6-7 in. (152-178 mm) of cable slack through the cable organization bracket, and secure each cable to the correct clips. Refer to the cable-organization bracket diagram for the clip assignments. 10.Place the bail-mount bracket over the cable-organization bracket and route the cables through the back of the bail-mount bracket. 11. Secure the bail mount to the surface using the four included 35 mm M 4.2 × 1.4 screws. 12.Follow the steps on page 3 to install the GPSMAP 700 series chartplotter on the bail mount bracket. Test the slack-length of the cables routed through the bracket. 13.Make cable slack-length adjustments if necessary.
