Hytera HM685 Digital Mobile Radio | Display DMR for Vehicles
The Hytera HM685 is the display-fronted twin of the HM655 — the same compact, powerful next-generation DMR mobile radio, but with a 1.45-inch LCD and piano keys on the radio body itself. It is the natural choice for a base-station desk, gatehouse or control room where the operator sits in front of the radio, and for drivers who prefer a traditional dash-mounted layout.
Why choose the Hytera HM685?
Part of Hytera's H-Series, it succeeds the discontinued MD-series mobiles with clearer AI-noise-cancelled audio, a 4-line display for channels and text, and 5–25W of output for coverage no handheld can match. Dual digital/analogue operation means it drops into your existing fleet and migrates with you.

Base station or vehicle?
Both. Add a power supply for desk use, or the included bracket and power cord for a vehicle install. It also pairs with the HR655 and HR1065 repeaters for full-site coverage — ask us to spec the system.
