The Furuno GPS Navigator -- looks like maybe a GP-31/GP-36 or similar -- is probably pretty good, if working. If it's a GP-36, it'd be a Differential GPS and you'll usually get very decent location info with it. Ours (from the PO's original installation) has 5 different screens with various info presented on each screen, anchor alarms, etc.... and works well, so we kept it as a back-up when we did a refit on most of the rest of our electronics.

If it's a GP-31 or GP-36, think of it as a chartplotter, with almost all the typical plotter functions except for a visual on the chart itself. You can likely find the manual on the Furuno website...
