yeah, well i have a viper on my other car, and just heard that its easier to get past. There is a Clifford Matrix dealer around here I just found out about, so thats where im gonna hit up, and see what they can do for me. As far as the proximity sensor... i would only be setting it to detect things in the car. So like i could leave the windows down, but if someone put a hand in the window it would go off.
