Open your file and send the waypoints/tracks/routes to the GPS using the "Send to device" icon. These items are stored in internal memory, not on the card. I *think* the same limits as my 60Cx apply - 20 tracks of up to 500 points each, "follow roads" autoroutes can be 50 points max.
Thanks Mike! That did it.
