I have an 08 V6 and went with a Fortin EVO-ONE remote start several years ago. It's a bit customizable with remote options, etc. I got the long range remotes too.
I got it through Crutchfield. The tech support is great there as well.
I put the one below in mine. I like the 2 way remote as I can tell that it started while sitting in my work cubicle. The T harness makes things much easier. They have good directions and tech support who seems to be decent. I think I've bought 4 remote starters from these guys and they have 20% off sales a couple times a year. Don't get one that uses the OEM fob as the distance is close to useless.
