Ok, here's what I've found so far:DEI is Directed Electronics, Inc and here is the link to the automatic start systems they sell:

From what I've read, it looks like the Valet is the system Diamond was referring to. Some of their systems have an option that lets you add a module (I think it's a GPS module from Viper) that let's you start your car over the phone! That would be really nice for me because I ride Metra everyday and could start my car from my cell so it would be warm by the time I got to my stop! I don't know how much that would run, though. There is also a model that has a remote with an LCD that gives you different information about your vehicle like the temp inside, if the door has been opened, and lets you perform a number of commands. Sounds really nice! I'll report back when I get some prices on different models with and without installation.
I found this site that has the LCD remote model for $199 with free shipping! http://www.caraudio-caralarms.....html
