Pretty impractical, but just reversing it, maybe OpenCPN should have an open standard protocol that the hardware manf. code to.
Agreed, but I have read that Garmin has their proprietary things to avoid using the GPS
together with e.g. OpenCPN on a computer. The only things they endorse is use their software i.e. Mapsource and the purchase
a second copy of their low priced charts/maps for use on the computer since the ones you just bought for your GPS
is not allowed to use on the laptop
My guess is they are in it for the money
not for user support or user friendliness. My personal opinion is that you can combine the above.
So this thread just took another turn, bu at the risk of nagging, still interested in what the GRMN mode in O
was implemented to support
