The part number for the screen is WD-F1624Y-7FLW which measures 2.6" (diagonal). a black rubber gasket is in place between the screen and frame. Both the display and touchscreen function.

While labeled "DAKOTA 20", the plate is compatible with certain other Garmin Dakota and Approach devices. The 2.6" is similarly compatible with certain other Garmin devices, including Dakota, Approach, and Rino 650/650T/655T.

NOTE: Buyer is responsible for ensuring compatibility. My advice to prospective buyers is to check the part number of what you have and are looking to replace.
