I have a clifford unit for about 450 at best buy, security remote start, and keyless entry. Lots of nice features, I have an auto, so I don't have to worry about the gears, Best Buy techs said to simply install another relay that causes the box to wait for that light to go out. They knew what they were doing and installed it for free. I love it. Oh, and for the long idle time problem, it only runs for 12 min. until I get the cold weather stuff working, then I can change the time on it.
Oh model # is clifford Matrix RS2.
