No AIS Targets on Garmin Device

When using an AIS device, if you are not seeing any targets, there are multiple things to check. 

1. Check the AIS Status Light; for more information on the AIS Status Lights and what they mean, click here.

2. If the AIS is connected over NMEA 2000, check to see if it is appearing in the chartplotters device list. If the AIS does not appear, troubleshoot the NMEA 2000 network. For troubleshooting steps, click here.
