In our Bav 40 Ocean we have a Raymarine C series plotter / radar and a suit of ST 60 instruments inclusive of auto pilot. Every thing is liked with sea talk (NMEA links) and appears to work very well. The C series plotter is a C70 and is located in the cockpit binacle. The ST 60 insturment below at the chart table gives read outs of the various functions to keep track of what is happening. We also have a second GPS, a Magellen complete with charts. This works well as the GPS for the Nav Station.
The C70 screen is a little small and when shared with the radar picture is too small – but it is price efficient and fits neatly in to the binacle.
