Garmin 128

Does Garmin 128 GPS have NMEA input/output? What can we do with it and what are the limitations?

It does indeed, and if you run a search on the forum, it will tell you how to wire it to a serial plug so that you can connect it to a laptop. In my last boat, I output to a DSC radio and a GPS repeater.

Yes
You can connect it to a plotter,autopilot or DSC radio.
We had to reduce the baud rate when connecting to a radio but otherwise it's worked fine.
It takes hours to enter waypoints so a plotter is much quicker.

OK thanks!

Mines connected to my JRC1000 radar. Puts the waypoint on the screen.

Once you've got the connector cable, you can use software such as Gardown or Waypoint+ to transfer waypoint data files that are easier created on your PC.
I use Gardown a lot; its source website seems to have disappeared but the link above has the software.
