trim caps and the device. Use a plastic pry tool when possible.
A flush-mount template and hardware can be used to mount the
device in your dashboard.
Trim the template and make sure it fits in the location where
1
you want to mount the device.
Secure the template to the selected mounting location.
2
Using a 9.5 mm (3/8 in.) drill bit, drill one or more of the holes
3
inside the corners of the solid line on the template to prepare
the mounting surface for cutting.
Using a jigsaw or rotary cutting tool, cut the mounting surface
4
along the inside of the solid line indicated on the template.
Place the device into the cutout to test the fit.
5
If necessary, use a file and sandpaper to refine the size of
