It is an exciting purchase for a variety of reasons when your company selects a GPS provider. The lights and sounds and "It can do all this and that" "Save you this and that" is a great ability these devices have however what you do not hear is the amount of work to track the devices to get that information.
A large majority of users, we experience, use the devices for knowing where the vehicle is, was, and when. (Brings up the question why are you paying more than $13.95 / month?) The shimmer and shine of diagnostics and fuel tracking the users find out it doesn't do it itself. The labor needed to set up the system like that does take time to set up and keep up with.
The Gps system you purchase CAN be a great asset but plan on only the basics in the beginning. Then add to your system as it needs. This is the most cost effective method in Fleet Tracking purchasing on top of using a NON CONTRACT company. We have yet to see the "contract" companies have happier end users than the "non contract" companies.
