Working Raymarine touchscreen chartplotter and 18" dome antenna model #RD418HD. This system works well for radar function and operating an autopilot, but I can't guarantee that all touchscreen functions work. I removed this from my boat to upgrade all the electronics. I am not sure of the age, but I am guessing around 15 years or older. The plotter is in a weather proof swivel stand mount. I do have the cable to connect them, it's approx. 40' long.
