Follow the instructions in this section based on whether you are going to complete a front mount or

rear mount installation.

Front Mount Installation

1. Insert a small tool (tip: a paper clip works well) behind each corner piece to pop out the corner
cover (see the illustration Front Mount In-Dash Installation). Set the corner covers aside.
2. From the front of the dashboard, with the control head screen facing out, carefully lower the
control head into the mounting hole.
3. Press down lightly on the control head. Confirm the control head is seated flush against the
dashboard. Make adjustments, as needed.
4. With the control head in place, use a transfer punch or pencil to mark the four corner screw
holes to the dash.
5. Remove the control head from the dash and set it aside.
6. Use a 3/16" (4.78 mm) drill bit to drill the four corner-mount screw holes.
7. Insert a bolt into the drilled corner hole. Remove the tape backing from the L-bracket nut. From
under the dashboard, begin to fasten the bolt to the L-bracket nut. Make sure the L-bracket nut
is aligned with the dash cut-out, and lift the bolt to bring the L-bracket nut to the underside of
the dash. Apply pressure to the L-bracket nut for 30 seconds to activate the adhesive tape, and
then remove the bolt.
8. Repeat for the other 3 L-bracket nuts.
9. From the front of the dashboard, with the control head screen facing out, carefully lower the
control head back into the mounting hole.
10. Apply a small amount of anti-seize to each bolt. Fasten a bolt into each corner hole on the
control head until it contacts the bottom of the nut. Hand-tighten only!
11. Use a #2 Phillips screwdriver to tighten each bolt an additional 3/4 turn. Hand-tighten only!
12. Replace the four corner covers.
WARNING! Do NOT use power tools to secure the hardware.
Rear Mount Installation
To install the in-dash mount bracket, you will need the gimbal knobs included with your control head.
1. Place the control head on a towel or cloth, with the screen facing down, on a stable and level
surface.
2. See the illustration Installing the Bolts. Install the carriage bolts (1/4" - 20) onto the bracket
with the flat washer (1/4" x 3/4") and seal washer (1/4" x 1/2") in the order shown in the
illustration. Hand tighten the washers fully until they are flat and secure on the bracket.
3. Line up the bracket arms with the ratchets on the side of the control head. The opening in the
bracket arms should face up (away from the control head ports). Adjust the bracket so it is
parallel with the control head screen. See the illustration Installing the Bracket.
4. Install the gimbal knobs into each side of the control head. Hand-tighten only! See the
illustration Installing the Bracket.
