Here in Florida, chilly to me is in the high 60's. Cold is 50's. When it hits 40 or below, we call FEMA.

But, even here, I try to keep my Yammie as close to room temps all the time, which means I don't leave it in a vehicle between jobs.

Gary just mentioned to me that cooler weather will affect the screen on his 3K. We both remembered when our old 740s would not even play until they warmed up in cooler weather. That, has not been the case with the later models however.

Your TY is tough, but I would not recommend leaving it in your vehicle during any extreme temps, hot or cold.
