I am interested in trying Garmin Basecamp for trip/route planning, but I know absolutely nothing whatsoever about how it works. I plan to do a Google and/or YouTube search for tutorials, but would like some advice from those who have actually used it as to its ease of use (or not). Billybovine, maybe you could chime in? You seem to know a lot about Garmin. I have a 660 Zumo. Thanks in advance.
