Compustar alarm/autostart system. Had it for a couple of years now and the autostart is great during winters.
One of the few systems that is compatible with manual cars. The autostart will not work unless you set it up by putting it in neutral and pulling the e-brake. Kind of a safety feature.
You can read about their systems on their site.
