So I've got a 192c complete with harness but it got dropped and the display is acting weird. We have already installed a replacement so I have no need to keep this thing around. all you need to do is send it in to Garmin for a refurbed one. I think they charge like 175$ for this model. That's a pretty good deal considering its a >500$ unit with all the bluecharts pre-loaded. The best part is the price! It's free. Maybe take me on a fishing trip or something if you are so inclined. All you have to do is be the first to reply and arrange pickup.
