G400 is a compact, multi-function GPS tracking device that provides an effective
management solution for rental
vehicles, construction-site vehicles, and personal vehicles.
With high positioning accuracy, G400 makes vehicle location tracking and route monitoring
fast, simple, and
stable.

A key highlight of G400 is its ability to automatically turn off the Smartkey knob if the user
forgets it for more than
150 seconds, helping protect the battery, reduce risks, and improve vehicle safety.
