It comes without any documentation, have some stupid questions, but not sure how to proceed. 1)can I just pop in a 128gm card, or do I need to format? 2)I saw in a DX90 thread some links on updating firmware, with no instructions, just links that start a download. Can I just download these and it'll upgrade automatically, or is there a link/site on where to install (the Fiio X3 had very specific instructions on updating firmware, for instance 3)I assume you had the card in to do burn in and charging. Have the dx90 plugged into my computer, would I be better off using the included plug (from DS, seems the answer is yes)
Thanks for any help
once you download the firmware, there are instructions on how to load new firmware with it. I would check to see if it has the new firmware installed on it already. It might be a newer batch DX90.
