Has anyone wired a Garmin 198C to a Uniden M525?
There are four NMEA wires on each and I have yet to make the right
connections; I do have the wiring diagrams for each item.
The Garmin should send time and position info to the Uniden, and the Uniden
should send received DSC info to the Garmin.



Just so you don't feel alone, I had this same problem with a Garmin to
Icom. Never did get it working right. On the list of Winter fixes. Look
forward to seeing a solution.
