Best Marine Garmin Gps Map For Boating On The Upper Mississippi River
I recently bought a boat with a Garmin GPS unit installed. I looked it up, and it is a $900 unit, but the tracking and detail are terrible.
I boat near LaCrosse WI, and according to the GPS unit, half the time I am on dry land. Garmin says they do not have any software that is any better. Has any one purchased a add on map that works on the upper Mississippi river ?
Here is Garmin’s web site to the Mississippi – not sure if it works with your unit. If not you can try to find a card from them that does:http://www8.garmin.com/cartography/g2vis…
