That's what I thought, Brian. Nope. The lock tab was in the correct postion. I cycled it a couple of times just to be sure but no change.
I have updated the charts and data before with this machine and this data card and all worked normally. Now it is giving the CRC Fail message and will not update stuff plus the SD card now says it is locked even thought the lock tab/switch thing is in the proper spot. I suspect that the CRC Fail message is most likley becuase the SD card thinks it is locked.
Maybe I could copy the contents of the SD card onto a blank card and see if things will work with the new card?
I will send a Support email as you suggested earlier. Thanks.
Happy New Year to all!
Bob
