Meh... I use my phone before I leave my office and by the time I get to my truck the AC is on as well as the AC seats if its hot out, if its cold the heat/heated steering wheel and seats come on <-- better feature
Cooling with remote start for 10 min. does absolutely nothing in south. The only way to get cabin habitable after sitting on sun and opening doors is, roll down at least front 2 windows, better all 4 windows and you still can't touch steering wheel for while.
I wanted to make this feature on my older 06 model and found me 12-24v operated boards having 4 relays with settable on/off delays and then i was gonna tap in driver door switches.
Chrysler managed to build this feature in and cancel it before i could upgrade to newer vehicle lol.
EDIT: which leads me to question if anybody knows if some flash code can reanable this feature for newer models...similar flash code like for DRLs
