In-Dash Mounting the Control Head
If you are in-dash mounting the control head, start by placing the components on the surfaces where you
intend to install them before installation. Make sure that the surfaces you have chosen provide adequate
protection from wave shock, and that all cables can reach the control head.
NOTE: If a cable is too short for your application, extension cables are available. Call Humminbird® Customer
Support at 1-800-633-1468 for more information.
Parts and tools specific to In-dash mounting are:
Threaded rods and hardware
In-dash mounting foam pads
In-dash mounting template
Reciprocating saw for cutting dash material
Masking tape to hold mounting template in place.
1. Locate a suitable, flat area of the dash to mount the control head. The control head requires a
depth of at least 4 inches (102 mm).
2. Tape the paper In-Dash Mounting template to the desired in-dash mounting location.
3. At a location inside the dotted line on the template, drill a hole large enough to insert blade of
reciprocating saw. In addition, drill the 4 mounting hole locations using a 3/16" drill bit. Carefully begin
cutting toward the dotted line, then follow the dotted line around the template. Remove the template
when finished.
4. Insert and tighten the four threaded rods into the four threaded inserts located on the back side of
the control head. Peel off the adhesive-backed foam pads and place them on the back of the control
head; make sure you notice the difference between the longer top/bottom and shorter side pads.
5. Insert the control head through the mounting hole from the front side of the dash. Place a
washer, lock washer, and wing nut onto each threaded rod and tighten fully.
6. Thread the cables through the opening in the back of the cable collector cover.
