[CA11] Axiom Pro Upgrade

We just replaced three e-series MFDs with Axiom Pro units (master 12" and two slaves 12" & 9") and have a few questions we hope you can help us with. Our radar antenna is a 12kW 48" Super HD array which was not changed. Software was 3.4 when installed and has been updated to 3.8.105 except for the radar unit update which repeatedly fails to update.

Thanks for your help!
