Most MFD, integrated avionics systems of glass cockpit systems that accept a weather radar input are compatible with the ART-2000. The Garmin GWX68 is not readily available on the used aftermarket and is higher in cost than the ART-2000 ($20995 vs. $18215 List Price). Furthermore, the Garmin GWX68 can only be serviced by the Garmin factory. Both systems offer most of the same desired features such as high power out, 90 degree scan, vertical profile scanning, and 10 or 12 inch antenna arrays
