The LCD screen on my 711 is fading and missing a line of pixels. Can the LCD be replaced? Can I replace by dropping in a newer 711C control unit while retaining my existing processor?
The 711 display is discontinued. You could purchase a Navpilot 711C display (https://www.furunousa.com/en/products/fap7011c) and update the software on your current processor to get a new display.
