Garmin GPSMAP 420 - Marine GPS Receiver Installation Instructions Manual

Installing the Flush Mount Kit
Use this kit to flush mount a Fishfinder 400C or GPSMAP 400 series unit into a flat panel.
• Select an appropriately sized location for the unit.
• Use the Flush Mount Template provided to determine a location.
• Check that all cables reach the unit mounting location.
• Always wear safety goggles and a dust mask when drilling, cutting, or sanding.
Included mounting hardware—(1) unit housing, (2) tension mount brackets, (4) hex bolts, (4) hex nuts, (4) wing nuts,
and (4) Phillips head screws.
Tools (not included)—drill, 3/8
To install the Quick Release Flush Mount Kit:
1. Cut the opening:
• Tape the Flush Mount Template to the mounting location.
• Using a 3/8" (6 mm) drill bit, drill the pilot holes indicated on the template to begin cutting the mounting surface.
• Using the jig saw, cut the mounting surface along the inside of the line indicated on the template. Be very careful when cutting this
hole, because there is only a small amount of clearance between the unit housing and the tension mount arms. Cut slightly inside
the indicated line and then sand or file the panel as needed to obtain the best fit.
2. Assemble the flush mount hardware (see Figure 1):
• Insert the (4) hex bolts into the unit housing so they stick out of the back.
• Use the (4) hex nuts to secure the hex bolts to the unit housing. Using the 9/32" (7 mm) wrench, tighten the nuts without
overtightening.
• Slide the unit into the unit housing.
• Using the (4) Phillips head screws, attach the unit housing to the unit.
• Connect the wiring harness to the unit (This can be done after step 3, if preferred).
