Viper is one of the best names for car security. Having installed them myself professionally for over a year there is nothing they cant handle. And if they cant handle it the lifetime warranty definately makes them superior!
On a more excited note, there is so many different things you can do with that auxilary button. You can have it control all your windows, you can have it turn on neons and such, you can have it power pop your door if you add enough of the right actuators and such (a little more difficult but definately an eye opener), you can have it do so many different things with the right relays and the right know-how that the sky is the limit. Have fun and enjoy!
