The GPSMAP® 172C fixed-mount chartplotter offers brilliant sunlight-readable color LCD, robust features, and a user-friendly interface—in a compact, value-priced console.

It comes standard with a built-in worldwide marine basemap and accepts MapSource® BlueChart® offshore marine cartography—featuring detailed depth contours, inter-tidal zones, wrecks, navaids, and many other points of interest. For small-water anglers, the GPSMAP 172C is compatible with MapSource Recreational Lakes with Fishing Hot Spots—featuring fishing areas, boat ramps, marinas, and hazards for hundreds of popular U.S. and Canadian lakes. Pre-programmed data cards can be easily inserted into the slot on the front of the unit.

For added flexibility, mariners can upgrade the GPSMAP 172C to a full-fledged combination chartplotter/sounder at any time by adding a Garmin® GSD 20 "black box" sonar and transducer.

90% really like, but....

GPS great....manual very explicit......easy to understand and follow.
However, Page vi of owners manual includes an optional "US A/C, PC Adapter", which is not available.
Had to purchase an additional "USB Data Card Programmer" to transfer MapSource data to the required data card.


Best value

I liked this GPS so much that I've purchased two in the last six months. It has a lot of features and is easy to use. This model also has the largest screen for the price that I could find. The only drawback is that it doesn't directly interface with a PC. The Garmin Blue Charts are good but not cheap. All in all I think it's a "best value" type unit.


Great Product.....Great Price!

I looked at a number of ChartPlotters before I decided to purchase the Garmin 172C from Amazon.com. I was very happy with the price, especially after hunting around for the best price around. Amazon beat everyone else hands down. And a "New Product" at that.

I am very happy with the ease of installation, and the internal antenna feature. I have not yet used the fish finding feature, however I plan to purchase the transcom and other associated pieces to use this feature as well.

I say, "Buy this product" if you are looking for a unit with it's sort of features (portable, internal antenna, etc). I'm glad that I did.
