Summary: Data bars top and bottom are totally balck and hide a lot of usable screen. Waypoints do not show up the same as old GPS and garmin homeport icons. Way points lay up on top of each other cluttering screen. Cannot select if waypoints shoe name or not. MY BOAT icon is waaay too big, again covering too much usable screen. Boat icon so big that when tryinh to hold up the boat icon covers the waypoint icon. Would not buy again until garmin updates software.
Summary: recived the unit as a plotter and sounder, the gps works great locks on in less than 1 min. but to use it as plotter you must buy a sd card or download one from garmin at a cost of around 160.$ the info screens are good ,unit don't convert td 's to lat lon. beware if looking for a sounder/plotter it should have a s behind the # like 520s not just 520. the one i bought was sold as a combo unit and was not. just a plotter.
Summary: For the money, this unit does everything well. The screen is clear and the detail is easily seen in bright sunlight. The only proviso is that a g2 card card is necessary if this unit is going to be used for navigation purposes.
