MOUNTING THE UNIT
The unit can be mounted on the underside of the dash panel of the
vehicle or in a DIN-size opening in the dash panel. It can
also be
mounted to the vehicle's floor "hump" using an optional hump-mount
bracket. The following instructions outline the mechanical installation
details.
1.
Select a mounting location. Confirm that the location is
appropriate as outlined in the section entitled
"PLANNING THE INSTALLATION".
2.
Using the mounting bracket as a template, mark six (6) mounting
screw hole locations on the mounting surface (dash panel, floor
board, etc).
3.
Using a No. 28 drill bit, drill holes in the mounting surface at the
marked locations.
