Flush Mounting the VHF 100/200 Series Radio
In addition to the four included 4.2 × 25 mm, panhead mounting screws, flush mounting the VHF 100/200 series radio requires the
following tools (not included):
• Phillips screwdriver
• Drill and 9/64 in. (3.5 mm) drill bit for mounting holes
• 3/8 in. (10 mm) drill bit for a starter hole
• Jigsaw
• Scissors and tape
• Center punch and hammer
• File and sandpaper
• Anti-seize lubricant (optional)
Note: Ensure that the surface on which you mount the VHF 100/200 series radio has sufficient open space behind it to accommodate the radio
and the connected cables. There should be at least 5 in. (127 mm) of clearance behind the case.
To flush mount the VHF 100/200 series radio:
1. Cut and trim the flush-mount template (page
series radio.
2. Tape the flush-mount template to the mounting location.
3. Use the center punch to indent the center of each of the four mounting-hole locations.
4. Use a 9/64 in. (3.5 mm) drill bit to drill the four mounting holes.
5. Use a 3/8 in. (10 mm) drill bit to drill a starter hole inside the corner of the template to
begin cutting the mounting surface.
6. Use the jigsaw to cut the mounting surface along the inside of the dashed line indicated
on the template. Use a file and sandpaper to refine the size of the hole.
7. Place the radio into the cutout to confirm that the four mounting holes are correct after
refining the hole. If not, mark the correct locations of the four mounting holes. Remove the
radio from the cutout.
8. Apply the gasket to the back of the VHF 100/200 series radio.
9. If the top and bottom snap covers are attached to the front of the VHF 100/200 series radio, remove them
by unsnapping the covers from the sides.
10. Place the VHF 100/200 series radio into the cutout.
11. Securely tighten the four mounting screws through the VHF 100/200 series radio into the drilled mounting holes.
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.
12. Place the snap covers over the mounting screws.
