Got factory RS on my 2014 Silverado and love it! I start my truck at work from my cellphone before I even leave my desk. Great in the winter to warm it up and melt shit off. Only drawback is it only runs 10 minutes, and I can only run it twice, so 20 minutes max. Which is long enough, really. Comes in real handy since I work at night, it can be damn cold and snowy at 6:30am in our parking lot.
