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.
NOTICE
To avoid potential damage to the powder coating, use only the included screws to mount the device. Using screws other than the ones included will void your warranty.
NOTICE
Do not remove the blue, rubber protective bumper until after the installation is complete. The bumper helps protect the device from damage during installation.
The included template and hardware can be used to flush mount the device in your dashboard. There are three options for hardware based on the mounting surface material.
-
You can drill pilot holes and use the included wood screws.
-
You can drill holes and use the included nut plates and machine screws. The nut plates can add stability to a thinner surface.
-
You can punch holes, tap them to M4, and use the included machine screws.
-
Trim the template and make sure it fits in the location where you want to mount the device.
-
Secure the template to the selected location.
-
Using a 3.6 mm (9/64 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.
-
Using a jigsaw or rotary tool, cut the mounting surface along the inside of the solid line indicated on the template.
-
Place the device in the cutout to test the fit.
-
If necessary, use a file and sandpaper to refine the size of the cutout.
-
After the device fits correctly in the cutout, ensure the mounting holes on the device line up with the larger 7.2 mm (9/32 in.) holes on the template.
-
If the mounting holes on the device do not line up, mark the new hole locations.
-
Based on your mounting surface, drill or punch and tap the larger holes:
-
Drill 3.2 mm (1/8 in.) pilot holes for the included wood screws, and skip to step 18.
-
Drill 7.2 mm (9/32 in.) holes for the included nut plate and machine screws.
-
Punch and tap M4 holes for the included machine screws, and skip to step 18.
-
If using the nut plates, starting in one corner of the template, place a nut plate
over the larger hole 
drilled in step 9.
The smaller hole 
on the nut plate should line up with the smaller hole on the template.
-
If the smaller 3.6 mm (9/64 in.) hole on the nut plate does not line up with the smaller hole on the template, mark the new location.
-
Repeat steps 10 and 11 for each nut plate.
-
Using a 3.6 mm (9/64 in.) drill bit, drill the smaller holes.
-
Remove the template from the mounting surface.
-
Starting in one corner of the mounting location, place a nut plate
on the back of the mounting surface, lining up the large and small holes.
The raised portion of the nut plate should fit into the larger hole.
-
Secure the nut plate to the mounting surface by fastening an included M3 screw
through the smaller 3.6 mm (9/64 in.) hole.
-
Repeat steps 15 and 16 for each of the nut plates along the top and bottom of the device.
-
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.
NOTE:
To prevent corrosion of the metal contacts, cover unused connectors with the attached weather caps.
-
Place the device into the cutout.
-
Secure the device to the mounting surface using the included M4 screws
or wood screws, depending on the mounting method.
-
Carefully remove and discard the rubber protective bumper.
-
Install the decorative bezel by snapping it in place around the edges of the device.
