One thing about the newer cars, also, is they depend on the radio to do other stuff important to the vehicle. So, if you want a real kick-butt stereo system, you're better off ordering the kick-butt sized stereo when you buy your new car. That's for those of us that used to put those ear drum damaging amps & speakers, along with the Craig 8-track players, in our old cars that came with the AM radio upgrade. But, the factory remote start is the best thing since sliced bread if you live where it snows and it's minus **^*)(^ degrees outside.
