Yes it is linked, so the heater or A/C won't blow out high if it will feeze you out more. There's a cabin sensor for the climate control & they do talk to each other.
The outside gauge checks too infrequently for my driving. (errands) & it reads the garage temp for quite a while. I have been at my 3rd store before I get it to read the outside temp, then when parked the engine heat warms it up! It's only meant to be close at 19 mph, on a day that's not too sunny & not too damp.
You're right the Pilot's seems to better located. Perhaps it's the height of it that helps. ?? It also seems to take a reading more often.
There have been several times that mine reads 55 degrees on a 40 degree day because that's what it was in the garage. Annoying? yes! It seems to work better in warm weather, when we bought it in August it was pretty much right on. So my assumption is that it's location is effected by the temps of the road suface & the engine more than they'd planned.
I printed out the "instructions" for checking it a couple of weeks ago & it passed when using a second source for reading the temp where it was parked.
It adjusts at a rate of about 1 degree per minute! (too slow for me!) If the first start of the day involves a cold engine it will have a new check for the outside temp. If it's warm it uses the last reading from before.
On freeway trips our's seems to be dead on!
If I find out anything is discovered about adjustments I'll pass it on!
