Waypoints are NOT on the map card. They are in the unit's memory.
IF you registered the Helix you will have a waypoint management computer software in your account--HumminbirdPC. Download and install it.
To get your waypoints to the computer, you EXPORT them to a blank memory card and then load them to the software.
