Just joined myself. I had a Viper remote start installed. Purchased at Best Buy with free installation. Comes with a key fob, they will also program your existing key fob, and I have the app on my phone. I love it. Price was around $300.
If anyone wants to install one on their own vehicles, just let me know, I have access to all factory wiring schematics, through Identifix. I also have installed quite a few of these systems myself and can give you any tips, or diagram info you may need.
