I may be quite a bit ahead of myself here but I still thought I would get the question posted a month or so before someone has the 2020 bolt in their driveway.
Q1. I have tried to google this to no avail. Does anyone know where the actual temp sensor is in this car? I would think it's somewhere in the dash because the other day my center screen read about 25 degrees hotter then the stated accuweather app. After about 15 minutes on Lowest hvac temp possible my Center screen read a drop from 115 F to 80 F (lower than the stated outdoor acuweather temp of 90 F. )
Q2. Is the default time out on the Bolt 1 our 2 hours before shut off? Also on the 2020's do they have a feature like "Tesla Dog Mode" where You can program the idle time to what You want (at least within the limit of what Your battery's energy can provide)?
Q3. on the 2020's how much clearer is the backup camera? Does anyone know if its possible to retrofit the higher resolution camera module into the older models? It would seem like this would be a very easy modification unless they changed the center screen resolution also.

I don't really have answers but I figured I'd give my thoughts. I read in another thread where the temp sensor is supposedly located up by the rearview mirror somewhere. Don't know if that is accurate though as that seems like an odd place to put it. As for dog mode, I seriously doubt it. It wasn't mentioned in the 2020 changes and doesn't seem like something GM would do. I also find it unlikely that just retrofitting the new camera(s) would make them work at higher resolution. The system is programmed to take a 640x480 feed (or whatever) so I would think the internals would have to be reprogrammed to accept the higher resolution video feed. Otherwise you'll put in (for example) a 1920x1080 camera but the system is still expecting a 640x480 video feed so all you would see are noisy horizontal smears (if anything) without reprogramming. Of course, they could have designed it to automatically scale based on the video output but that's probably unlikely as it would be extra coding that they didn't need at the time.

I still get no consistent behavior out of the temp readout. Some days the temp drops 20+ degrees when I blast AC and some days it stays consistent (very high at over 100 F like it did today).

I stumbled across this information while randomly browsing for parts on one of the GM retailers. The temperature sensor is indeed in the windshield dustpan:

The backup camera on the '19 Bolt is much better than the backup camera on my old '08 Prius. You get a truer picture of distance and more clarity. I also had a '13 Prius, but it didn't have a backup camera.

I wonder if my sensor is faulty? The plastic on the rear mirror felt hot due to the car sitting outside all day in almost 100 degree Texas heat. After I ran my HVAC it felt cool but my car temp only dropped from 102 to an even 100 - HVAC was set to 65 degrees and it definitely felt like around no more than 70 in the car.

I'm confused. I didn't think our Bolts displayed inside car temperature, but only displayed outside temperature. I know the car has to use a temperature sensor in order to control its own HVAC, but I didn't think the actual temperature is displayed.

I agree. I don't know of anywhere it shows the inside temperature. Only the outside temperature. Which in my experience is usually about 2 degrees F above the actual outside temperature - on all my cars past and present, not just the Bolt.

You may be on to something. The temperature on the display is the outside temperature and that can change drastically as you start moving. Most cars have a built in delay where that temperature may not update until you start moving in order to avoid things like heat soak while sitting at lights, etc. So it can show one reading when you start the car (it's a "left over" reading from when you parked it) and after you've been moving for some seconds/minutes and the car has some airflow around it, it decides it's time to update.

Yup. The center screen displays outside temperature. measured by a thermistor in the center of the lower grill. The interior temperature sensor, and a humidity sensor, are in the box on the windshield, behind the rear view mirror. The HVAC system reads those, but there is no driver display for those.

That outside thermistor is effected by pavement temperature, and sun exposure when the car is sitting. Once it is rolling down the highway the temp will drop to match the air temperature.
