I have 2 mfd12 displays.had 2.05 software which I just upgraded to 2.07 incremental.i did this in hope of getting depth finder display to stop jumping to different depths but it made no difference.i decided while I was doing update s I would put in 2.13 update.after reset and disconnecting cables update seemed to fail and I now can only turn unit on and it beeps every few seconds and screen flashes. Tried master reset again and it will not reset.seems software is corrupted and messed up unit.was going to download software again and start over and hope this would get unit going..I have a 2 gigabyte card and a 32 gigabyte card.i think either should work but I have been having trouble getting unit to read card after downloading software and sat photos. Unit can see card in slot but says there are no files .on my computer I extract the files and can see them on my scan disc .does scan disc need to be formatted a certain way. Any suggestions appreciated. Bill
