Totally forgot I could precondition with the FOB - I've been doing it via the app and it's a bit slow for my taste when I'm getting ready in the morning. Not having to precondition just yet since our highs are still 85 in Texas, but bet your ass it's going to come in handy in about a month I have Level2 charging in the garage, so it's going to be awesome getting into a tosty (and charged) car... going to suck ass when leaving work and it's been sitting out all night (i work nights) without even being plugged into a basic 120V.I use an alarm clock on my smartphone to remind me, then I press the buttons on the fob. RemoteLink takes too long (app talks to onstar through the Internet, onstar calls the car on a phone, sends commands, hangs up.). Make sure you are i\parked outside or have the setting set to not allow ICE while preconditioning and make sure you are plugged in. Yu don't want to build up exhaust in a closed garage.
