store crop/variety calibrations like DRC. Option for Remote cal switches/key pad at aircart. Integration with relative flow blockage. Backup settings to usb/ops centre. Better protection of wiring harness from UV. Red and yellow wires perish after 5 years in Aust.
Scale integration, dynamic calibrations, faster set up & edit, tank fill monitoring (w/ability for remote display to have at the tender), not using PWM boost boxes with the 2000 was a nice upgrade from GRC, ability to use boost pump for nh3, DI communication w/GRC-like doc, etc…
