Navdata (frequencies, etc) can also be out of date in as little as 28 days, but Garmin allows you to access that for much longer. I don't know the actual expiration policy for navdata. If you're using foreflight to look up frequencies, etc then you don't need that either. The obstacle and terrain data changes rarely. Shorelines don't move (much) and tall buildings don't get built in a day. Again, it's up to Garmin how long they'll allow you to use that data. In short - you can't guarantee the data will still be around in six years. Is the 650 actually prohibiting you from accessing it for navigation? If the 650 is still useable, I'd skip the garmin subscription and continue to rely on foreflight. I have a 530 in my 337 that has completely out of date data but is still useable for VFR. Edit: Now I see your edit! The data went poof! I think that's a 650/750 "feature" = I don't think the 430s and 530s do that. I'd call Garmin and ask directly.

An update for those who may have a similar problem in the future.
Spoke to Garmin. The navigation database does NOT delete automatically after X years. It should be there and I should be able to get it back by restoring the unit to its default state. Will check and advise when I go to the airplane again. Ernie |
