Hi, SD cards from different manufacturers might be different and we haven't tested with Transcend SDHC  Class 10 before. It is hard to say will it work on MD802 or not. It would be nice of you to share your experience once you try it. 

 I've got a 32gb Sandisk Ultra MicroSD HC card in an SD card adapter which works great in my MD802. With all the most latest updates as of today, the MD802 software seems to take up around 8gb of space. This Sandisk is a class 10 card.
