Hello, this issue has been touched on quite a bit, with indications that you can use a handheld GPS
like the Garmin
Etrex to give a GPS
position to OPEN CPN
on a Mac. I want to setup a backup system based on OPEN CPN
and a Macbook Pro and the handheld offers a flexible option - can be used to help with paper chart navigation
if the electrics go down.
Some forum members seem to say that you can and others that you need an NMEA
compatible device and that the Garmin's USB won't do the job?
