NOTE: The illustrations in this manual may not look the same as your product, but your product will function in the same way.

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:

• Interference: The mounting location must provide adequate distance from electric motors or any equipment that may cause electronic interference.
• Stability: The mounting area should be protected from waves, shock, vibration, and water.
• Depth: The mounting area should have a depth of 3 inches (7.62 cm) to allow space for the control head and cables.
• Ventilation: The area beneath the mounting surface should be well-ventilated.
• Accessibility: The location should be easily accessible for all cables to reach the ports on the back of the control head.

NOTE: If a cable is too short for your application, extension cables are available. For assistance, contact Humminbird Technical Support through our Help Center at https://humminbird-help.johnsonoutdoors.com/hc/en-us.

HELIX 5 Series In-Dash Mounting Dimensions

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:
   • Drill one entry hole away from the main cut line that is large enough to insert the blade of your cutting tool.
     OR
   • Drill a corner hole away from the main cut line using a drill bit that will create a hole as close to a diameter of.42 inches (10.7 mm) as possible. Repeat for the other three corners as indicated 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.

Install the Control Head

1. Clean the Mating Surfaces: Use rubbing alcohol to clean the edges of the in-dash mounting hole and the back rim of the control head where the gasket will be installed (see the illustrationInstalling the Gasket). Allow the cleaned areas to dry completely.
2. Place the control head, with the screen facing down, on a towel or cloth on a stable and level surface.
3. Peel the brown liner from the adhesive backing on the gasket.
4. Hold the sides of the plastic film attached to the gasket with the adhesive side facing down (see the illustrationInstalling the Gasket). Carefully align the gasket around the rim of the control head so it is centered. Confirm there are no uneven gaps.
   
   Use caution when handling the gasket. Do not allow the adhesive to touch the sides or rear of the control head during installation.
5. Lightly press one side of the gasket down onto the flat rim of the control head.
6. Confirm the alignment has not changed and that the gasket is centered around the control head. Then lightly press down on the remaining sides of the gasket. Make adjustments, as needed.
7. Carefully peel the plastic film from the gasket.
8. Insert the control head through the mounting hole from the front side of the dash. Press down firmly around the sides of the control head for 20 seconds to secure the adhesive.

Route and Connect the Cables

1. See the installation guides included with each hardware component to install power and other optional equipment.
2. Route all cables (power, transducer, accessories) to the control head and insert the connectors into the correct ports on the back of the control head (see the illustrationConnecting the Cables and Control Head Ports).
   
   Do NOT mount the cables where the connectors could be submerged in water or flooded. If cables are installed in a splash-prone area, it may be helpful to apply dielectric grease to the inside of the connectors to prevent corrosion. Dielectric grease can be purchased separately from a general hardware or automotive store.
   Your control head is ready for on-the-water operation. See your control head operations manual for further details.
