I picked one up a couple of months ago as I wanted a 2nd
GPS chartplotter. I have the older
Garmin 478 which I love but is no longer made.
I've hooked up the 620 as the primary at the
helm and the 478 in the masters
cabin and used mostly as
anchor alarm and general good feeling when in a new anchorage.
Still getting use to the 620. As with all new toys it is different than the 478 some better features and faster turn on, but some I still prefer how it worked on the old 478 but most of that is I am just use to it.
Like the touch
screen much more than I though I would. The way the 620 sets up a track for
navigation is more visual than for the 478 and probably simpler... once I get use to it.
So far no complaints about the 620, it is just different from what I'm use to using as would be any other unit other than another 478. Guess I'm getting old and more set in my ways
