Thanks for your advice
I don't know about the Brown NMEA out off the garmin. But the outer wire on the ICOM should be earth (did allot of searching on the net to find this out).
I wouldn't go connecting the Brown on the Garmin to anything until you find out better.
Connecting like I described has given me time, date, location etc info on the screen of my ICOM 411.
