70 dollars. Not sure if anyone posted this. Briefly read it and the reviews. Appears to operate off text messaging or pager technology and gps. Has geo-fence feature as one of its activation features, will locate your vehicle and can remotely shut down your car too (probably has a relay, you can do what ever with it)
