[CA11] Axiom 7 - network error - SPx5

[sgloster]

I'm in process of adding a new Axiom7 to my boat, however when I go to add transducers to the Axiom it displays the error "Manually selecting source of Depth is not supported while the following devices are on the network: SPx5 S/N: 0000000." My autopilot is an SPx5 with a p70 head - I'm able to update the firmware on the Axiom, on the p70, and on my i70 to make sure they are all up to date - however - I'm guessing the SPx5 also requires an update? Is this the cause of my error? Is there a way for me to update?
