Lowrance HDS7 Generation 1


New member
I have wired mine HDS up to a Garmin 300 AIS (NMEA183) receiver. The AIS indicates it is receiving data (Power light on and flashing receive light) but I cannot seem to get targets on my HDS display. Have also swopped the data wires/polarity around but still no joy.
In the HDS menu for AIS there is only the option to block AIS target not enable.
Anybody have any ideas.
