I've got a Garmin NUVI I use for land based navigation but I'm wondering before I shell out 100 bucks for Garmins PC map of the Great Lakes if the NUVI will upload GPS coordinates to the Garmin maps via the USB port. Anyone done this?
If it doesn't work with Blue Charts then that pretty much takes care of that idea. I'll just get the coordinates off the NUVI and plot them on paper (backup to the chartplotter).Are you talking about getting the BlueCharts for the Great Lakes? If so, be aware that the MapSource program no longer does live tracking of the GPS. Garmin, for some reason, cut out the program's ability to track the GPS in realtime a few versions back.
However, depending on what model Garmin you have, you may be able to use it with something like SeaClear II, with the right driver for it. Then you could use the free ENC or BSB charts from NOAA. However, these will only cover the US waters, and you'll probably be missing the Canadian waters. The Garmin BlueCharts cover both.
