The problem is when I upload the maps to the card the maps already there are
deleted. So how do you upload from Blue Charts and City Select without
deleting one or the other?

I just purchased the Garmin 276C and I got the Automotive Kit and Blue

the memory card at the same time or will I need to switch cards when
moving from land to sea and from sea to land?

So long as you have unlock codes for both, they should display OK.
