Please Note: MapSource Fishing Hot Spots provides coverage for selected lakes throughout the United States and Canada. Selected lakes are contained in predetermined geographical regions which must be unlocked prior to use. With the purchase of MapSource Fishing Hot Spots, customers will have access to one region of their choice at no additional charge. Unlocking a region can be done through Garmin via our unlock webpages or by phone. Additional regions may be purchased through the same methods. Click on a region of the map on the left to view a complete list of the lakes and use the Map Viewer on this page to see the actual lake maps.


When using a locked MapSource product, the real-time track plotting function will work only with a valid unlock code for the GPS unit being used.
