who makes a good one ??
i have seen the GPS by Viper which is Tele track ,
Is it on line all the time , which means does it keep track of the car all the time ? not like the lo- jack which has to be activated .
Also i was told that you need an alarm to go with it . is this true (im planning on also getting an alarm )
If the alarm is cut or disable (since they say you need an alarm with it
Does it disable the GPS system ???
what are the pros and cons of this system ?
thanks
