Trackmate GPS Mini 3G H Vehicle Tracker - Concealable GPS Device - Real Time Hardwired Location Tracker for Cars - 5 Pack

This is the 3rd GPS tracking system I have installed to try and get to work with reasonable functionality. I have tried Vyncs and MasTrack and Trackmate is by far the best solution. The unit itself is very well engineered so you can unplug it from the wiring. The online software, both web and mobile based is excellent. You can get any report you desire or real time location.

Simple and they work well
