If you have not already done so: register your unit on the Humminbird web site. You will have access to the HumminbirdPC download (also available on this web site). Install it on your computer and you can view your waypoint, track and route data there. If you want to see this data against a map background, you will also need to download and install Google Earth. You can than have the HumminbirdPC program display the selected waypoint(s), route(s) and track(s) against the Google Earth background map.
