[CA] [CA11] Axiom 12 with Navionics Freezing on Bootup

[argus]

I have a Axiom 12 and Axiom 7 networked together with the Axiom 12 as the DataMaster. When I leave the boat, I turn off both Axiom using the button on the screens and then I turn the master battery switch off on the boat. When I turn the Axioms back on, with the Navionics chart card in the remote card reader slot, the Axiom 12 will power up but when I select chart, it freezes, shows a blank screen and will not respond to screen touches; bootup sequence continues to cycle and I cannot turn it off. However, the Axiom 7 is displaying the Navionics chart that is in Axiom 12 remote card reader. I have to remove the Navionics chart card from the Axiom 12 remote card reader card reader, wait until it completes new bootup, wait a few minutes and then put the Navionics chart card back inAxiom 12 remote card reader - then all works.
