| Plan the Mounting Location
Start by locating a suitable, flat area of the dashboard for mounting. Consider the following to find the best
mounting location:
Δ Interference: The mounting location must provide adequate distance from electric motors or any
equipment that may cause electronic interference.
Δ Stability: The mounting area should be protected from waves, shock, vibration, and water.
Δ Depth: The mounting area should have a depth of 4½" (114.3 mm) to allow space for the control head
and cables.
Δ Ventilation: The area beneath the mounting surface should be well-ventilated.
Δ Accessibility: The location should be easily accessible for all cables to reach the ports on the back of
the control head.
Δ Multiple Control Heads: If you plan to install more than one control head side by side, leave a minimum
space of 5/8" (15.9 mm) horizontally or 1/2" (12.7 mm) vertically between control heads. Take your
measurement from the front edges of the control head. See the template for more information.
NOTE: If a cable is too short for your application, extension cables are available. For assistance,
contact Humminbird Technical Support.

| Cut the In-Dash Mounting Hole
To in-dash mount the HELIX control head, start by placing the components on the surfaces where you intend
to install them.
1. Review the instructions, measurements, and cutting options indicated on the In-dash Mounting
Template.
2. Tape the template to the chosen in-dash mounting location.
3. Using the template, select the cutting method that is best for your boat:
Δ Drill one entry hole away from the main cut line that is large enough to insert the blade of your cutting
tool.
OR
Δ Using a 5/8" drill bit, drill the 4 corner holes (inside the main cut line) as shown on the template. Use
one of the corner holes as an entry hole, or drill an additional entry hole away from the main cut line.
4. Carefully begin cutting toward the cut line, and continue cutting to the inside of the line around the
template.
5. Test the Mounting Hole: Install the control head in the mounting hole to test the fit. Make adjustments
to the mounting hole as needed. Remove the template when finished.
6. Thoroughly clean and deburr the mounting hole.
