This unit is absolutly fabulous. I love all of its features from remote start to turbo timer (where u can leave the car running while the doors are locked and take the keys with u. It will shut off after 3,12,ect minutes however long it is set for). The features are great. It works exactly as described. Also, you have to love 2 way where it tells you when your stuff is broken into. I have a battery backup and extra siren and i would recomend it to anyone.
