[CA] [CA11] A80440 RCR-SDUSB Operation with Navionics+ Chart Card

[Dan_Y]

Can the A80440 corrupt a Navionics chard card? Just installed the A80440 and was able to save Axiom screen captures to the 16GB MSD card in the A80440 while the chart card was being read by the Axiom. I used the axiom to eject the card from the A80440 then loaded a LH3 latest version .iso file on the card, then inserted the card into the A80440. The Axiom found the card automatically and the upgrade went smoothly.

After the upgrade, and restart, I used the Axiom to ejected the Navionics card from the Axiom and the .iso file card from the A80440. After inserting the navionics card into the A80440, the Axiom could not find the Navionics card in the A80440. Turns out the Navionics card index file became corrupt and could no longer be read by two other PC computers.

I was still able to read/write the .iso file card in the A80440 after the Navionics card was corrupted.

I have removed and replaced the Navionics card many times to update the charts. Is this just a very odd coincidence?
Thanks,
Dan
