Attention

Most boats run on two batteries, each 12 volts, combined in series to provide 24 volts of power. In the diagram below, the battery on the left is the ENGINE BATTERY. Its positive lead goes to the engine and its negative lead is tied to the positive lead of the HOUSE BATTERY on the right. The HOUSE BATTERY’S negative terminal provides the common ground for the boat’s electrical system. The RGHR2 runs on 12 volts. Hence, for trouble-free performance, connect the BLACK GROUND WIRE and the YELLOW POWER WIRE of the RGHR2 to the corresponding terminals on the HOUSE BATTERY only. If the BLACK GROUND WIRE does not reach the battery, it can be connected elsewhere, but it may cause intermittent issues. The safest bet is to connect the ground wire directly to the negative (black) terminal of the HOUSE BATTERY. Be sure to connect the RED (ACC) WIRE from the harness to the vessels ignition. This will allow the RGHR2 to power on when the vessel starts up.

A color-coded electrical wiring schematic illustrates how to connect a gauge-style marine head unit to a dual 12-Volt battery system consisting of an ENGINE BATTERY (left) and a HOUSE BATTERY (right). Head Unit Connections: Accessory Connection (ACC): A red wire with an ACC label connects from the receiver to an ignition key switch symbol. Constant Power Connection (+): A yellow wire labeled with a + sign connects from the receiver directly to the positive (+) terminal of the HOUSE BATTERY. Ground Connection (-): A black wire labeled with a - sign connects from the receiver to the negative (-) terminal of the HOUSE BATTERY. Battery System Connections: Engine Battery Power: A red power wire leads out from the positive (+) terminal of the ENGINE BATTERY with the text OUT TO THE ENGINE accompanied by a lightning bolt icon. Battery Jumper Link: A thick black cable connects the negative (-) terminal of the ENGINE BATTERY directly to the positive (+) terminal of the HOUSE BATTERY. System Common Ground: A black ground cable leads out from the negative (-) terminal of the HOUSE BATTERY with the text OUT TO THE COMMON GROUND POINT accompanied by a lightning bolt icon.

Poor or no radio reception

  • Make sure antenna cables are properly connected.

Bluetooth pairing fails

  • Check to see that both devices are turned on and that your Bluetooth device is discoverable.
  • Turn both devices off and then on again.
  • Make sure you've selected the proper source.
  • Make sure that the Bluetooth device is within 5 feet of the unit.
  • Move both devices away from other Bluetooth devices and/or other electronics.
  • Make sure that the unit is not paired to a previously paired device.
Files on USB memory device will not play back
  • Make sure you've selected the proper source.
  • Make sure that the audio files are properly formatted.
