Pre-programmed datacards:

Pre-programmed datacards are immediately ready to use. Simply unpack the card and insert it into your Astro handheld. These maps do not need to be unlocked to your device which allows you to move the card to multiple units if desired, however you will not have access to the mapping on your computer.


Maps purchased in this format will require a computer to use but will allow you to plan trips on your computer and transfer waypoints, routes and tracks to your Astro handheld. The installation process will install the mapping and the MapSource application to your computer. MapSource can then be used to send maps to either your Astro handheld or to a datacard.
