WARNING - impossible to install due to cable connector / mounting arem incompatability. Do not purchase !!
25 July 2014
Summary: this is the most badly designed unit I have ever purchased. It just DOESNT WORK as shown. The picture shown is impossible to replicate due to the cable connector sticking out too far. If the mounting bracket arms were 0.5 inches longer the cable connector wouldn't snag on the bracket, but the arms are too short. If you install the cable you need to cut away the cable guard in order to get the unit to sit horizontally. Tilting upwards is impossible.
Summary: Like others I thought I was getting something else. I didn't understand that the detailed maps were extra, in our case the map card for the area we boat in, the great lakes, costs more than the chart plotter itself. I have since ordered one, what else can you do? From other standpoints this little unit is very nice. The display is bright, controls are pretty easy to use, setup was not too difficult.
Summary: I bought this unit as a secondary to mount on the helm of our sailboat. Main GPS is in the navigation station below and I wanted a unit on the helm to allow me to stay at the helm but still keep the information handy. It works well. able to see current location, speed,track, etc... without going downstairs. First trip to catalina we ran into 1/4mile vis fog and it worked great.
