[GPSNavX]

Both GPSNavX and MacENC has the ability via NMEA data to plot tracked targets and the cursor of a RADAR on the chart. You would want to look for a RADAR that supports these NMEA messages..

$RARSD, $RATLL, $RATTM

Any RADAR that supports those NMEA data messages can be connected to the Shipmodul Miniplex Lite multiplexer.
