Always good to know that my knowledge is correct. AFAIK Caymans ship with the one-touch windows up or down from the door panel activated, as well as having the window drop a little when the door handle is raised making it easier to open/close the door and still seal the window well. To get the auto window up or down from the REMOTE you need to have the
Mods4Cars RemoteKey product installed. The same for auto-unlock, Porsche only gives you auto-lock as an option that can be turned on. And you've already noted that the increase in delay time from Porsche was minimal as compared to the
Mods4Cars solution, but probably better than nothing without it...
