For the first time in years, my IFly 700 failed in a way that was not solved by rebooting the unit or disconnecting and connecting the SD card. I had just flown for about an hour and a half. Upon my return to the airplane, when I attempted to get the IFly started, it showed a failure in the sectional.exe routine. The only available option was to quit. Upon quitting, the screen came back to the home screen. I rebooted several times and ejected/inserted the card to no avail. That day I was not able to wake it up at all.
I just updated the sd card this morning and, other than the weather, the only other new version of anything was a WAC chart. Even though the expiration on the installed one was 2/5, the update indicated that there was a different version with the same expiration date. I performed the update and now the IFly works fine.
Was there something wrong with that particular file? I thought that unless you updated software, the sectionals were just files and not "exe" routines. I was not using the WAC chart at the time of the failure. My serial number is MB110249 and I am running version 7.5.20
