Was thinking about getting an auto-start next month and was told the python auto start with the smart start app (same app as viper) was a good one, I wanna get rid of the fob and use my iphone 5s, and it has a range of literally "anywhere" as long as u have a cell connection, this could be a great alternative to the weak key fob problem in our cars. Plus less bulk in your pocket and operating your car with your phone is pretty appealing... Anyone have this system?
