This is the Chelton nemesis.  I have been using xD cards with an
adapter as per Tim Olsen (check his site
http://www.cheltonefispilots.com/forums/) with good success.  In
general format in FAT not FAT32.  Use a PC (I am a mac user and
sometimes the formating doesn't seem to work).  If after you put the
card in and apply power, you do not get to the maintenance screen, do
a soft reboot - press both round buttons at the same time.  If none of
these work, try it again.

Good Luck
