Just curious if any of you have experienced this. I have a non-WAAS GNS530. Out of nowhere during a flight I get a message about a memory card being removed. After landing, I powered the unit down, removed and reinserted the memory cards and powered it up with no luck. I reprogrammed the memory card and it appeared to successfully program and verify the data, but upon inserting it and turning the GNS530 back on, I still got a series of messages that stated "No Jeppesen Aviation Database." On the GPS status page, it says "TER FAIL". Other error messages include "No basemap data available", "No Terrain Database Available", but it says "US Obstacle Database and has the old date from 2005 and there's a US Airport Terrain Database version and cycle as well.
I'm thinking that maybe my navdata memory card is bad and the first thing I'll try is to find someone who has a non-waas 430/530 and try their navdata card. I was just curious if anyone has seen these and could tell me that their experience was a bad data card as I'm not particularly fond of the thousands of dollars it would cost to do an unplanned WAAS upgrade.
