What an easy installation. With the left-hand helm, I mounted the GPS antenna on the mounting stud for the port midships cleat with a nylon-lined backing nut. Because of the dash-panel thickness, I had to install the recall switch along the port-side gunwale so I can reach it easily when I want to check my top speed after a run. Wiring was straightforward. Using heat-shrink butt connectors, I followed the easily deciphered instructions to power the gauge and recall switches, and the red back lighting is easy on the eyes at night. I'll have an update in spring 2015 when I get the boat on the water. Until then, check out www.livorsi.com.
