Garmin Inland Lakes Vision South Central microSD/SD Card | Marine Electronics

I bought this to put on my Garmin Nuvi 1450 and it works very nicely for telling you the contour of the lakes, where the boat ramps and marinas are, common names of points and coves and rivers on the lake, and parks and camp grounds around the lake. I'm pleased with it and it has definitely met my fishing needs and wants. They usually tell you the depth in 5 foot intervals. The only colors they use are black for deeper water and red lines for shallower water with the depth wrote in feet on the lines. I wish they would have fancied it up a bit more and used more colors to make it a little easier to look at but none the less, it is still a fairly good contour map. After reading on the Garmin website, I thought this came with more features such as "fish eye view" and stuff like that, and I haven't discovered that it does that after using it for over a month. So maybe it does have it but I sure haven't seen any signs of those features.

I will say there are no instructions that tell you how to use and activate this on your GPS. I had to sit on the phone with Garmin for about 45 minutes to learn how to use it, so I will save you the time and trouble and tell you how. In order to use it on the Garmin Nuvi 1450, you must go to "tools", "settings", "map", "info" and then check "US Inland Lakes" and uncheck the base map. You have to do this every time you want to use it on the water and then undo it to use it on the road. The principle is to let the GPS focus on the water maps and not the road maps and vice versa for what you are using it for.

Overall, good product and glad to have a car GPS that is also handy on the water!
