What if you have neons, a really loud system, or you take off fast with some nos and dont know a cops around, its good to have some sort of security. And also you can be like, (YOU: Hey dude I just got this brand new rader with this jammer no cop can get me know./ YOUR FRIEND: Wow, thats tight, how much it cost?/ YOU: 300+/ YOUR FRIEND: Man your loaded/ YOU: yeah man its all about the bling bling) << Just kiddin! Naw, I dont thing the passport can work unless you got the 8500 or whatever it is. V one can't control it.
