2000C Display
I've been flying with a 2000C since it first came out and I don't believe that's possible (to display the airport name instead of the identifier). Your screen would be totally cluttered and unreadable, at least here in Texas where there are many, many airports.
Also, when setting up a route or just a go-to destination, you really need to know the identifier to get a proper preflight briefing so stick with the norm.
Just my opinion.
Good luck, I hope you enjoy the Lowrance as much as I do, and fly safe!
