Ive got a Garmin 60CS handheld. Its got about 55mb of useable memory, if my mine serves me correct.
I can put all the maps of UK, France and Spain and some Med. From Atlantic Bluechart v 9.5.
Thats way more than I need.
I had an etrex before. Screen way to small.
Biggest drawback with the 60cs is still the screen size. But as a portable/ back-up it works for me.
Yes extra maps are great but with a limited amount of memory the basemaps are very low in detail.
That makes no sense!!!!
If I was going to the States I'd the the new version (below). Plus a proper plotter.
