Inside the boat there is often a channel or conduit used for other wiring, this can be used to route cables.
Be sure to route the cables as far as practical from the antenna cable of VHF radios or tachometer cables
to reduce the possibility of interference. The GPS receiver cable should not be cut, and care should be used
not to damage the cable insulation.
Basic installation tasks that you must perform include:
• Installing the Transducer
• Installing the control head (choosing either gimbal or in-dash mounting)
• Installing the GPS Receiver
• Testing the complete installation.
