I believe to view your map chip on your PC you need the "Nav Planner" software and the navionics card reader. The maps wont work in a standard SD slot on a computer. Also, if you have the PC version as well as the mobile version, you can enable "sync my data". This mirrors all your routes/waypoints, etc on your PC and your phone, so when you add a new waypoint on either, it's automatically view-able on the other.
