[CA11] Axiom Speed Issue

I am having a problem with a newly installed Axiom 9 RV. It is showing 0 MPH for SOG on all screens. It has software version 3.8.105. I talked to Mark in support today and he had me do a factory reset which I did but that didn't fix the issue. Unfortunately I didn't have the best reception and got disconnected before we could troubleshoot further. I have GPS fix and the boat is showing properly on the chart, but no SOG data...

Thanks for any help,
Adam
