I am looking at a mid90s sailboat with this GPS setup.

Is anyone familiar with the unit.

thanks

The 492 is a model before Garmin came out with the 44x and 55x series. IIRC, it has the US coastal charts preloaded and can be used with a sounder as an option. The user manual for it can be downloaded from the Garmin website, here.

I had a 492 on my previuos boat. It was an excellent unit for the price.

Excellent Unit...

Slightly less resolution that the new 5x5 units but still good. Good daylight viewing. I prefer using the "highway' view on this GPS when sailing to a waypoint, which is not available on the new units. No need to upgrade unless you want a bigger screen.
