Used 2100 display in good working order for sale.  You can still buy autotrac activations for this display, and it can also be used to replace a brown box greenstar display on older air seeders, planters, and combines or an 1800 GS2 display on newer air seeders.  I will sell them either separately or together.  The 2100 display does everything the 2600 GS2 display will do, but uses the scroll wheel and buttons to navigate on screen instead of touchscreen.  Starfire ITC receiver pictured has already been sold.
