We're thinking of buying a new Garmin GPS. We don't need a plotter

find to buy a Garmin GPS without also paying for the built-in plotter
is to get a 152. When we looked at the Users' Manual for the 152, we
found the NMEA output port (listed as being for an autopilot, but will
work fine with the PC) and two input ports. Problem is, they're noted
as being for a 'Beacon Receiver' and a 'Device with Sonar Output'.
Can we use those lines to upload waypoints from the PC? If so, how?

Buy a handheld, there are dozens to choose from.

Do you think I should? This is the main navigation device on our full-
time cruising boat, and we rather like having a built-in display at
the nav station indicating things like position and bearing, time and
distance to the next waypoint. I grant you those are echoed on the
laptop and at the helm, but we actually to refer to the mounted unit
pretty often. Also, does that solve my problem about uploading
waypoints directly from the laptop?
