Information please. Recently bought two new machines and opted for the CAT GPS Visionlink radios and dashboard. Very cumbersome and diffcult to use. I utize Aware GPS asset trackers on my other machines and vehicles. Comprehensive map and have the ability to see all vehilces, in real time. Can anyone tell me what trackers you use and the service. And if you know if these machines have OBD ports. You can also reach me at firstname.lastname@example.org.
