The 276c remains one of the most useful units Garmin ever produced. I
still use mine, but mostly on the screen showing estimated arrivals, SOG
etc. In other words, I use it as a trip computer. One thing about these
units is that at some point, the internal button battery wears out and
the unit will stop holding settings. This happened to mine a couple
years ago, and I was able to find information on how to replace it, and
suggestions on exactly what battery number is needed. It is a special
button battery with leads welded to it so it can be soldered to the
circuit board. You cannot directly solder a button battery to anything.
This repair was well worth the effort involved. That said, I'm not sure
chart updates are even still available, and I bought a newer Garmin with
included charts and a bigger brighter screen to use as a dedicated chart
display.

Ahoy!
We love our old Garmin 276C. It is time, however, to upgrade. Should
we upgrade our BlueCharts? If so how? Or should we get a new
GPS/chartplotter altogether? We have the Raymarine ST-60s on the boat
already.
We sail NYC to Maine.
Thanks,
