GPS - VHF connections

[markpoint]

Hi, I am trying to get a GPS signal to my Cobra Marine DSC VHF.

GPS signal coming out of a Navman Trackker 5110

Manual for Tracker says

Pin 1 Black = Ground - power neg Nmea
Pin 2 Brown = Power out 9v DC
Pin 3 White = Nmea out - to autopilot/radar !
Pin 4 Blue = Navbus - or Nmea2 Input
Pin 5 Red = Positive Power in 11-16.6v dc
Pin 6 Orange - NavBus+
Pin 7 Yellow = Auto Power in
Pin 8 Green = External Bleeper or light out swithc to ground.

Shield is connected to 1 Black.


Connection to Cobra DSC VHF is via a 2.5mm jacvk plug - red & Black wires.

Manual for VHF states

Connect NMEA out negative to black wire
&
Connect NMEA out Positive to the red wire.

VHF and Tracker work great on the own - Tracker Acquires sats and GPS is good.

Cant get the GPS into VHF - Keeps blowing fuses.

Voltages to both are good - any help appreciated.

Navman white connects to Cobra red.
Navman black connects to Cobra black.

You need to check the Navman's Comms set-up to ensure that "Autopilot out" is enabled.
