You likely have climate settings configured for remote start in the vehicle. On the IPC/gauge cluster, the left side screen under Vehicle Settings there should be a menu for Remote Start and it has various options. Applies to both remote start via the fob and the app. For the settings with Auto or 'Last Setting', Auto will automatically run the HVAC at desired internal automatic settings, regardless of what you previously had your HVAC controls set to, even if they were off. I believe it aims for a set temp of 72f and whatever the preferred vent configuration would be (usually foot vents for heat, face for A/C, front defrost kicks in below freezing out). These cannot be changed. The settings it aims for on Auto mode are hardcoded. 'Last Setting' is obvious and will simply follow what you had the HVAC controls set to previously. As far as firmware updates are concerned, I think the general consensus is to not do them unless you have a specific thing you are trying to fix that has been documented as needing an update. Especially on the more mission critical modules like the PCM, BdyCM/BCM, IPC, and the hybrid related modules. A failed update on any of those will make the car entirely inoperable. Less critical modules like the TCU/Modem we've been dealing with here, APIM, ACM, and others will just cause an inconvenience but the car will still -usually- be drivable.

... I am honestly SO Stoked about this!! Taking the car back to the dealer would have been a big hassle, and I don't think they would have known what to do about it. Everybody on this forum is a frikkin legend! ?

@bookemdano and @GeR2 I just did the update. The whole effort (starting from downloading the software) took me about 45 min thanks to the amazing guidance that you've put up on this thread. Everything works - Happy Days!! Thank you both so much! One follow up question - when I hit the start button on the app, some sort of air conditioning/heating comes on in the car. Is there a way to set the temperature for this? And also, does it matter whether the car is plugged in or not? Another follow up question - now that I have this cable... Are there any other super safe and easy updates/upgrades that you suggest I consider? Thanks again!
