Without reading the reams of paperwork both devices came with does anyone know how the radio should be connected to the GPS please!
If the Cobra only has one pair of wires for NMEA then they will be the NMEA in - you will need a manual for the specific Lowrance (they are available online) to find out which wire is the NMEA out on the GPS. Often the NMEA negative wire goes to earth so I would assume the black on the Cobra either goes to the same earth as the GPS or to the equivalent.
Hope that's clear, it's easy once you know which wire is which!
