Well everyone seems to be trying to talk you into PC software, which
isn't what you asked for. Since I was the first to do it, I guess I
can't cast asparagus. Back to your original question. From a glance
at the catalogs, it looks as if the CMAP media are supported across
the most product lines, but not Garmin. Given your stated concerns,
I'd probably pick a CMAP unit I liked and make sure the freeware
worked with it before buying.
