navpod

One of my first projects on my 1986 Ericson 38-200 was to replace the old instruments and get a chart plotter. To mount them, I went with a NavPod, including one of their pedestal guards and a top plate adaptor that they make for the especially for old YS/Merriman pedestals. The old stuff was...

NavPod Pre-Cut For Garmin 2006/3006/3206. Like new condition. New was over $350. I will sell for $250 plus S&H.

I am trying to open the Navpod housing that holds my chartplotter. They used these screws that look like an Allen head screw with a post in the center. I suppose this is anti theft? How the heck do I get into the unit? Would like to try and remove the chartplotter.... Thanks, RT
