In attempt to take on General Motors' OnStar system, Chrysler's Mopar division has launched its own vehicle telematics system.

Chrysler's Mopar parts division has announced the launch of a new tracking system that aims to compete with General Motors' OnStar system. Dubbed Electronic Vehicle Tracking System (EVTS), the system is now available through authorized Chrysler, Dodge, Jeep and Ram dealers.

Compatible with Chrysler vehicles with a 16-pin diagnostic data port, the system consists of a small GPS unit that plugs in behind the vehicle's dashboard. The system costs $459 - not including installation - and offers nationwide vehicle GPS tacking at no extra charge.

Two step-up plans are also available, putting EVTS on par with GM's OnStar. For an annual fee of $149, EVTS buyers can upgrade to Mopar's Silver plan, which includes "Security Fence" (a feature that lets owners set speed and distance parameters for that vehicles), text alerting when Security Fence is broken, arrival/departure information, maps of the vehicle's past locations, 24/7 emergency dispatch services, automatic theft notification and OnCall, which acts as an on-board panic button.

If you want even more out of EVTS, a Gold plan is also on offer for $249/year. Including all of the features of the Silver package, the Gold plan adds unlimited online vehicle tracking and a full concierge service that allows for directions to be sent right to the vehicle. Using the EVTS services requires the use of a registered cell phone.
