The Micro SD card does not match the printed type (white labeled and no orange). In addition, it is slow (about Class2; tested with s several programs and in direct comparison with an existing map the same type). Furthermore, the size of 2GB is displayed larger than with a card of the same type (well something ...). When writing grösserern files and / or high level occurs data loss. No Caption on the back (like other Samsung Micro SD card). = No use>, send them back. Whether the card is probably Samsung ???
