I like the 76 that I buy several year ago so much that I want another in the same series when I upgrade . this be so much quicker , and it have so many new feature , especially greatly increase memory , and it cost considerably less than the 76S . the one thing I have find lack be that the tide feature the 76 have only come with another $ 120 + of marine software for the 76CSX . we live near salt water and it add to the usefulness when we be camp if we know what the tide be do . be there anyway I can download this into my new GPS ?
