IFD 550/440 Nav Data Updates

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Recently after updating JDM to the latest version (not by choice--forced JDM update), I am having a recent issue uploading Nav database updates to the IFD 550/440. The error I now get when trying to update the Nav database on an IFD550/440 says "Error detected Copy Non RF Nav Database Files". IFDs are running the latest 10.2 version. I see another similar post, but that seems to be about RF data on a 10.3 device so a little different. I update Nav databases regularly, so the previous Nav data update was fine. Anyone else running this issue and if so what did you end up doing that fixed it? I'd rather not update to 10.3 if I can help it. Waiting on Avidyne support as well. Thanks!

	There have been several reports of this issue and we're working to determine the root cause. Generally speaking, reformatting the internal compact flash memory card will fix the situation. But when you reformat, all of the nav data, obstacles, charts, terrain, configuration files, options, etc. get wiped out and have to be reloaded. So we'd rather have you do that only as a last resort. There's a chance that we can generate a new nav data DSF for you that will work temporarily. You can coordinate that through tech support.

	Thanks. We tried updating to 10.3.1.2, but unfortunately the error still persists. Haven’t heard back from tech support yet but hopefully they can email me a NavData file that works.
