Route the wiring harness to the power source and to the
device.
2
Connect the red wire to the positive (+) battery terminal, and
connect the black wire to the negative (-) battery terminal.
NMEA 0183 Connection Considerations
• The installation instructions provided with your NMEA 0183
compatible device should contain the information you need to
identify the transmitting (Tx) and receiving (Rx) A (+) and B
(-) wires.

Updating the Device Software
Before you can update the software, you must obtain a
software-update memory card or load the latest software onto a
memory card.
1
Turn on the chartplotter.
2
After the home screen appears, insert the memory card into
the card slot.
NOTE: In order for the software update instructions to
appear, the device must be fully booted before the card is
inserted.
3
Follow the on-screen instructions.
4
Wait several minutes while the software update process
completes.
The device returns to normal operation after the software
update process is complete.
5
Remove the memory card.
NOTE: If the memory card is removed before the device
restarts fully, the software update is not complete.
