The MicroSD card provided is used indiscriminately on the Garmin Edge 800 series or 62st and also by BaseCamp application by connecting it to a USB port on your PC with a suitable card reader.
The supplied DVD, unfortunately, can only be used on a single PC once it has been used to activate it with the code provided. Once validated on a PC, do not try to use that DVD on another PC, it will not work because of the copy protection. I personally do not use it.
