The advantage on your boat is that the NAV screen is not located in a recessed pocket like on my 2000 380DA. My pocket was tall and narrow, like the electronics of that era.
Your boat will permit mounting almost anything. Pick something that will cover the extent of the existing cutout.
Go into your local marine electronics store, like West Marine, to select and purchase the nicest system that will fit.
When I upgraded mine in 2003 I put the E120 (Now Classic) that was brand new at the time. It has been a great choice / upgrade.
