Errors Loading Data Updates

It is very interesting this FOB corruption issue.

Today I tried again to update the IFD-540 with a new JSUM download from Jepp.  I had charts, navdata and obstacle data on the thumb drive The charts loaded normally but as soon as the navdata went active, the bar graph immediately showed 100% and the IFD-540 hung.  I power cycled after about 5 minutes and the box came up normally with the current charts and navdata but expired obstacle data.  I checked the thumbdrive on my computer and everything had been erased.  There wasn't a single file on it.  I will try to get Jepp to give me a new obstacle data load and see if just loading that (without charts or navdata) works.  Despite all the problems with loading data, my unit appears to work normally otherwise.

Just solved the issue. The touch screen option was turned off after the upload. I did not change the setting. Go figure!

Will need to call Jepp tomorrow to get another copy Very frustrating Have not flown my my aircraft MVFR or lower because I don't trust the unit. And the reason I haven't requested to receive my second unit for installation Where are we at at correcting this problem?

Hey Leonard, we believe this issue will be corrected with the 10.1 software release.

Still no reports that I'm aware for this issue with units loaded with 10.1.0.0.

We think we resolved this with 10.1.0.0 but still very interested to hear if any 10.1 box is having database update issues still. 

Steve,

For the first time in many months, I tried to update the CHARTS.DSF file without formatting the Avidyne supplied stick.  540 updated okay, but when I tried to update the 440 it just did "Querying USB drive . . . .", then rebooted into a loop.  Gave up and brought the stick home and Windows 8.1 shows it has the mess of garbage files with the 1980 date, just like before.  Both the 440/540 have version 10.1 installed.  Below is a screen shot of the stick contents.

As an aside, for the first time , the "GPS Dead Reckoning" hit me on the 540 for about 30 seconds right after takeoff today, but the 440 was okay.  I just installed the 440 last week, but don't know if that would cause the problem.  440 is working fine in all respects.

Let me know what files you need and I'll upload them to a cloud account for your access.

I got my #2 IFD back from Avidyne on an RMA where they did the 10.1.0.0 update the hardware mods, and now it's guaranteed to happen 100% of the time after a chart update.  Sometimes that unit will reboot into the infinite loop prior to finishing which takes you back to square one.  The reboot into infinite loop is a new feature since the RMA.

Lately, I've just kept extra copies of the USB stick data and reformat the stick, recopy the files and try again.

I was hoping it was the MLB100 which corrupts the pressure altitude from the encoder on the IFD when it's negative so today I tried it with the MLB100 turned off. For me the MLB100 install coincided with the RMA and my MLB100 only feeds #2.  No luck, while the update completed on the first try it still mess up the USB stick.

FWIW #1 is rock solid with respect to updates.

Just had this problem today on my 540.  Interestingly, the navdata loaded just fine on my 550, but when I try to load it on the 540 it gets to 66% and then craps out.
