Canadian Angler. I have to pick your brain..This has to do with Garmin Echomap Plus 94sv. I have done everything you showed in your set up videos. I am confused with the map in this unit. I live in Wisconsin. I have just finished the download of the maps.. Must I get a chip from Garmin to see the lakes in my state in detail? Contour Lines, Depth, humps ETC. When I select something on the maps that are in the Garmin, I don't get the depth or contour lines I had Humminbird and LakeMaster and Navionics chips.. NEED HELP ! Thanks in advance...Dennis
yes you need card for your area. mine came preloaded with all of Canada yours should have come with your area if you bought it in your area.if you ordered online or some thing you may need to buy that upgrade.you should be able to do this online and download it to a sd card.
