5. Align the GPS receiver screw holes over the pilot screw holes and attach with the #8 - 1 1/4"

the mounting surface.
No Access Under Mounting Location
Follow these steps to deck mount the GPS receiver in a situation where you must route the cable to the
side because there is no space for a cable underneath the mounting location.
1. Determine the best location, then test route the cable from the mounting location to the control
head.
NOTE: AS-EC10 10' extension cables are available from Humminbird® if your planned routing exceeds 20', (6 m).
Maximum cable length, including extensions, should not exceed 50' (16 m).
2. Confirm the cable length is good and route the cable from the receiver to the control head. If
holes are required to route the cable, they must be 3/4" (19 mm) to allow for the cable connector.
Secure the NMEA cable with electrical tape.
NOTE: Remember to seal screw holes and drilled holes as needed with marine-grade silicone sealant to protect
your boat from water damage.
3. The GPS receiver has two wire routing notches. Use the cable notch closest to the intended cable
route.
4. With the cable routed, position the GPS receiver in the planned mounting location and mark the
mounting holes with a pencil or punch.
5. Move the GPS receiver to the side and drill the two 9/64" (3.5 mm) pilot holes.
6. Align the GPS receiver's screw holes over the pilot screw holes and attach with the #8 - 1 1/4"
Phillips head screws. Hand tighten only!
