Seen this system on another site. Seems pretty good
"Arrow Track GPS. Its a live tracking GPS system for cars, trailers, boats, RV's. There is no waiting for police, You track your vehicle yourself on a private Internet account. It covers the North American Continent including Canada.
You can track and keep an eye on your ride from another state if you want too. Best of all the GPS calls you when a problem occurs. So there is no waiting to discover somethings wrong. I put a Geofence around my car for added protection, so if my car gets a 1/4 of a mile away from where it should be, I get a second call from the GPS.
The system is backed by 27 satelittes and communicates through first tier digital cellular networks. Its a GSM Quadband. There is no monthly fee. The first year of air time is free with purchase. You pay 99.95 a year starting in the second year for service. Best of all its an American product"
