[CA] [CA11] Heading vector needs to be updated

[AndrewSimon]

Lately every time I turn on my E120W, the heading vector is not correct to the boats course. I correct by "aligning heading" via GPS on my E12196. The course then is correct until I turn off the instruments. Am I correct that the instruments should be receiving power for the memory even when the circuit breakers are turned off thru the Seatalk system?
