Outside temp display useless?

Within a degree or two of the NWS temp when I'm driving by thier sensor - can't ask for better than that. The startup delay is to prevent high temp readings due to heat from the car itself.

Same here - mine almost always matches the local airport reported temperature. Only time it doesn't is when it is a hot day and I am stuck in rush hour traffic ....

I agree with that post. You just have to wait a little bit and the results get shown right. I have had this system in my 05 Vette and 2 Silverado P,U, trucks. It even gives you a ice warning if the temp gets close to 32+-. That saved me late one night comming home as I was zipping right along on a mountain road with the P.U. and failed to realize the elevation change brought me into colder weather.
I had just finished a hard day and my senses were not in "sharp driver mode"
I saw the display saying ice, and carefully made a brake test. Could have been a problem if I had hit the brakes hard or went into a turn too fast

If the outside temperature goes up, the displayed
temperature will not change until:
• The vehicle’s speed is above 10 mph (16 km/h) for
five minutes.
• The vehicle’s speed is above 32 mph (52 km/h) for
two and a half minutes.
These delays prevent false readings. If the temperature
goes down, the outside temperature will be shown
when you start the vehicle.
If it has been turned off for less than three hours, the temperature will be recalled from the previous vehicle operation.

I have to drive a mile or two. That takes a couple of minuets then mine is accurate.

It does take a few minutes, but that is the way it is supposed to work as I understand it. Mine appears to be very accurate.
