RE: Miss April Question was to easy.mix and match ?
If the Garmin is the newest uni you have, and you want to build a new system around it, you may want to start over. I have a 2010C I got off the internet a couple of years ago, and it was being discontinued even then. It will interface with an autopilot and depth/sonar, but I cannot find anything that shows it to be radar-display capable. I also have a 192C plotter at my lower helm station, and though it's also an older model with a smaller display, its screen redraw is much faster than the 2010.
