[CA] [CA11] Navionics Chart Data will not load and MFD reboots

[Robinsonh2o]

I have 2 Axiom 12" displays and 1 9" Axiom Pro, networked together all with the 3.9.46 software version. I recently updated my Navionics 637P+, which includes sonarchart shading when you activate sea aerial overlay. The chart loaded as it usually does when I first turned on the MFD with the updated navionics card installed. The aerial overlay was in "land". I switched the aerial overlay to "land and sea" and the MFD attempted to load the chart but ended up freezing the display causing a reboot, which now happens every time I go to the chart app. I have since attempted to switch back to land only but the charts will never upload. I tried a factory reset which did not work. I also tried the card in a non-data master MFD which also did not work. I tried to update the card through navionics in case there was something wrong with the update, that also did not work.

Any ideas what the issue is?
