It doesn't do anything at all.how does the 496 behave when the data base expires? Does it bombard you with messages until you update it or does it just remind you when you turn it on?
That's for the portable products. The first message on the GNS-430/530/w on power-up is the database validity dates. It doesn't warn you per se, but you do have to acknowledge the validity dates before the unit will go into operating mode. Since I use if for IFR, I do the monthly updates.None of the Garmin products do any warnings about the data bases being out of date during flight that I'm aware of. I think most guys update only 1-2 times a year.
Snake bit? Sounds like you have "Vista" on your computer!how does the 496 behave when the data base expires? Does it bombard you with messages until you update it or does it just remind you when you turn it on?
