| Install the Bracket
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.

| Install the Control Head
1. From the front of the dashboard, with the control head screen facing out, carefully lower the
control head into the mounting hole.
NOTE: If the control head will not fit through the mounting hole, remove one of the gimbal
knobs and angle the control head into the mounting hole. Replace the gimbal knob before
proceeding to step 2.
2. Press down lightly on the control head. Confirm the control head is centered and flush against the
dashboard. Make adjustments, as needed.
3. From under the dashboard, insert the vertical bracket holes over the bolts. Ensure the top and
bottom of the vertical bracket is evenly aligned and flush against the dash. See the illustration
Installing the Vertical Bracket.
NOTE: If your vertical bracket has multiple bracket holes, use the center bracket holes.
4. Install a flat washer (1/4" x 3/4") and hex nut (1/4" - 20) onto each carriage bolt. See the illustration
Installing the Vertical Bracket. Use a 7/16" adjustable wrench to hand-tighten the nuts until the
assembly is secured. Then tighten no more than 2 additional turns. Hand-tighten only!
Do NOT over-tighten the hex nuts. The bracket should remain straight without bending.
