Sounding more and more like I don't want this feature. I have an aftermarket starter (AstroStart)that I've had on my last 3 cars. You can start the car and the doors stay locked until you push the door unlock button. If someone did get into the car and hit the gas/break pedal, the car would shut off. One buttom start, buttons are kinda recessed so no unintensional starting. I can programe the car to automatically start at 3 different temps (27*, 0* and -10*) every 15 min or half hour for either 5 min or 10 min at a time. Really works great here in Chicago in the winter. It has one of the longest ranges I've seen for a remote. I can start it from my desk on the second floor - rear of the building. Only drawback was the installation. It was $200 and took almost a whole day to install it correctly and I had to give up one of my keys. But the wife and I are 1000% satisfied with it. Will never have a car without a remote start. I may just go with that instead of the complicated sounding factory one.
What if you have your hands full and you have to press 2 buttons at the same time seems inconvenient.
OOOps, just re-read previous post before sending this. I see it's sequentially not at the same time. I still like the features on the AstroStart.
Probably will go with the factory remote due to the complexities of modern cars electronics. I will check with my installer. So far this is a great site, even though I haven't got my terrain yet.
