I installed this after purchasing from Ebay and there is a number that you need to call to activate the system... well I called and it is always busy. I asked one of my friends and he said its because they are always changing the activation number. I called directed electronics and they said I need to have a Viper Installer call because the have a direct line to directed. So I went and noone knows what Im talking about. Anyone on here know anything about this. I have the Viper 1020 Gps Tracking System.
