Huh? [needing to drive over 40]
I notice that short parkings result in the gauge pretty much showing the last reading.
Overnight in the garage, it shows "sorta close" to ambient in the garage.
But it starts showing the correct ambient after a few minutes even when traffic keeps me stopped at lights and well below 40.
Once it starts showing correct temperature, it seems to stay within 1-2 degrees of ambient measured against a weather bureau grade mercury thermometer...
Dunno if they can be reprogrammed or not if they are off...
