I am trying to connect my Lowrance HDS9 Gen 2 to my Uniden um280 to utilize the gps or dsc function. I followed the instructions in the Uniden manual for both the gps connection and then I followed the connection for a chart plotter and cant get any information from the Lowrance. I thought I made to appropriate setting change in the Lowrance but I am not receiving any info.

I’m confused.

You connect 2 wires between the chart plotter and the vhf.

Connect transmit (TX) on chart plotter to receive (RX) on VHF.

Grounds from both units get tied together

I will give it another shot. I thought I had everything connected correctly. Should I leave the wires connected for an extended period before throwing in the towel

Connecting to a GPS Receiver:

First, Connect the Yellow wire from the radio to the positive transmit/+NMEA out wire from the GPS.

Next, Connect the Green wire from the Radio to the negative transmit (-NMEA OUT) wire from the GPS Receiver..

To finish, If your GPS Receiver does not have a negative transmit (-NMEA OUT) wire, connect the Green wire from the Radio to the GND wire from the GPS Receiver
