I recently purchased a 2018 Cayenne S and miss having remote start like I did on my MDX. I live in the Chicago area and we have a large high-end electronics and appliance seller called Abt. They install a variety of aftermarket auto electronics and do a nice job. So, I called them about adding a remote start to my Cayenne and the sales rep told me that they can bury a key fob in the dash and somehow connect it to a dedicated fob that tricks the buried fob into starting the car remotely. But you must give up a key fob to make it work. The $600 cost of the install is mostly labor. Has anyone had any experience with this type of remote start install?
