Yeah, these things are off. It's like a plague and has been brought up in several other threads. My truck almost always says it's below freezing and 99% of the time it's well above. It even drops a couple/few more degrees when the truck starts moving. I guess it's measuring wind chill factor, too.
I've got a $1000+ weather station at my place, and I monitor other people's weather stations in the area on Wunderground and these trucks are way off. Kinda frustrating.
