Viper Responder 690xv

[XDRKMANX]

I was looking into buying the a Viper 690XV alarm for my car.

I wanted to know if anyone has any information about this alarm.

What do I need to buy to have this alarm work on my Grand am. I know there's something I have to buy because of are factory alarms.

Thanks
