[CA] [CA11] Axiom 9 RV Sounder issues

Raymarine vs. customer config follows:

The issue would occur in chart/sonar mode or sonar only mode. All other settings were on auto. There are no other MFD's in my set up. My system does have a RS150 GPS antenna which has been selected as the system's GPS data source.
