The software allows you to select a geographical area and enable waypoint categories for that location to be transferred into the receiver. Using DataSendTM After you have installed DataSendTM you are ready to view and send waypoints to the receiver. While running DataSendTM you will see a background map of the world that you can zoom in to see enabled waypoints. If you want to send waypoints to your receiver, you must select the geographic area first, then from the waypoint list you can make your selection of waypoints to send. The software will compute the amount of memory required and whether your selection fits into your receiver. If it exceeds the available receiver memory, either the geographic area, list of waypoints selected, or both, can be decreased and the memory requirements recomputed. The list of waypoints selected in the specified geographic area can then be saved under a project name you enter. You can then send the waypoints to the receiver which replace all waypoints in the receiver. The default waypoints that came with the receiver can be restored at any time. Don't worry about losing the waypoints that came with the receiver, they are available on the CD for retransmission to the receiver.
