Thanks.
I did set the Garmin for NMEA. But not initially. It wasn't until I got home
and remembered that my other Garmin's have to be changed from Garmin to NMEA
depending on what I'm doing with them.
(They are handhelds, and I download my tracks to my PC.)

First, make sure the GPS COM1 is in NMEA mode. Garmin, IIRC, ships their
units in Garmin
mode.

Now the wiring:
GPS Blue (NMEA out+) to VHF white (NMEA in +)
GPS Brown (NMEA in +) to VHF green (NMEA out +)
Ground to VHF Yellow (NMEA in -)
Ground to VHF Orange (NMEA out -)

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.
