I have the Viper SST 5900 Alarm with (Hello....Your Car Is being Broken into now.!) feature which transmits up to one mile...it comes standard with Remote Start.
Works great in the winter as I have the Seat warmers on hi as well as the blower and heat on full. My butt gets nice and toasty when I get in.
Go to your local Viper Dealer.. Can only be installed by them.
Here's a site to give you and idea of what it can do..
