I didn't arm mine last night while at a concert at The Masquerade. Of course, everything in the back seat pockets was tossed to the floor. I don't usually keep anything of value in the jeep. I lost a Gerber multi tool and could tell the cb had been f'd with (my mirror right below the cb was all screwy). I typically will not arm it if I have to park in a remote location where I or anyone else will hear it. Last thing i need is a dead battery and a jeep that's been broken into.
I like the Vipers because they will alert you via text msg if something happens. A friend of mine said he paid $495 for his Viper installed at 4WP Norcross.
