Some installations require "hard-wired" devices and in many instances a user friendly Plug And Play device can be utilized. As of 1997 every vehicle manufactured in North American, and most other countries, has been equipped with a standard OBDII diagnostics port *. Generally located under the dash near the steering wheel column, this OBDII port allows mechanics to scan the engine computer and determine if a vehicle has experienced any malfunctions. It also provides a perfect location to easily install a full service GPS tracking device. This small Plug and Track device is simply inserted into the port allowing for an installation time of less than 5 seconds in most cases. GPS and Cellular antennas are built into the unit and power is provided by the OBDII port. Because the installation requires no wire connections the unit can easily be moved from vehicle to vehicle by non-technical personnel.
Because fleet size requirements can change often overnight, this GPS tracking device is perfect for a company that might only lease additional vehicles for weeks or months to complement their fleet without the need to have technicians install, remove and reinstall hardwired devices.
In addition to ease of installation, these devices also provide limited monitoring of Engine Computers in vehicle classes up to 1-ton's.
While OBDII is the common standard not all manufacturers use the same pin configuration or protocols for diagnostics. This is especially true of high end and import automobiles.
