2 of my friends have the Garmin ECHOMAP Plus 95sv. I've seen how well they work and my friends rave about its ease of use - much more user friendly than other makes. When I saw it for less than $950, I bought one, installed it myself, and after first use, I'm happy. Basic use is explained on-screen. Excellent graphics and easy to use touchscreen. The only issue so far is that the display is too bright at night, but I'm told it is adjustable - I just need to read the instruction book. Spray the rear connector pins with WD40, or similar, to avoid saltwater corrosion.
