The SinoGNSS P300 Plus is a rugged, in-cab Android tablet built on ComNav's K8 platform, pairing a 10.1-inch 1280x720 touchscreen with an octa-core processor, 4GB RAM, and 64GB storage in an IP66-rated, aluminium-magnesium alloy shell. Integrated 4G LTE, Wi-Fi, and Bluetooth 5.0 let it pull RTK corrections and run precision-agriculture guidance software, backed by full-constellation GNSS tracking for heading and positioning. It serves as the in-cab display and control unit for ComNav's AG501 Pro and AG502 autosteer systems, showing guidance lines, machine speed, and steering controls.
