[CA] [CA11] Axiom Pro RVX Course Up Issues.

[PetrelMarine]

Hi Chuck

Can you please help me with an issue I am having with a newly installed Axiom 16" PRO RVX. This unit was installed replacing an E140W, integrating it as far as possible with the original equipment installed. I have attached a layout of the system. The issue I am having is as follows.

i. Chart behaves erratically in Course Up. I have tried every possible configuration but when the 16" display is placed in Course Up orientation, the chart does not orientate to display the course to the noon position. I've tried so many different motion and presentation settings to try and get the unit to behave normally and still cannot get it to. I have not seen this behavior with other Axiom units, it's utterly confusing and defies any logic whatsoever when underway.

ii. The COG as displayed by the unit 16" whilst using the internal GPS, which is set as the manual selected GPS, can sometimes be significantly off from reality. I have checked it against another independent GPS and manual compass, and have sometimes seen it differ up to 30 degrees with no tide/drift conditions . Again, totally odd behavior.

All other equipment and operations work just fine except for this issue and I am completely at a loss as to what to do next.
Thanks.

Matt
