Have 93 echo map sv. Mapping seems to be off about ten feet according to depth on depth finder with new g3 card. Anyone have any idea why?

Mapping is spot on in my lake. Strange
Every where I go
It's my understanding that you have to buy the 200.00 map upgrade to be able to change the depth. It was inferred by Garmin tech support when I bought it that it would be automatic. I think that you have to enter the depth change manually?
