Page 13: Selecting A Location
SELECTING A LOCATION It is advisable to spend a little time selecting the best location for your GX750. The radio is a modular design which allows the main unit to be discretely mounted out-of-sight behind the dashboard or control panel. The chosen location should provide sufficient space to reach the connectors and allow some airflow for the heat sink. - Page 14 DC connections Connect the RED power lead to the Positive (+) side of the battery or to an accessory point in the vessel or vehicle’s fuse box. Connect the BLACK power lead to the Negative (-) side of the battery or to a ground point in your vessel or vehicle.

During installation, try to route the DC battery leads, the antenna lead or any accessory wires away from the engine compartment, ignition or alternator wiring. -
