Unless you live where there are actuall subzero temperatures often, this is a bad idea.

*That blanket thing could burn yer car down. Worst case scenario, but it exists.

*That blanket thing could run your battery down. Forget to unplug it one time and come out into the cold after a gig and your keyboard won't be the only one freezing their butt off...

*For a half hour trip, this is a non-problem. The car heater will also have something to say about the ambient temperature and even if you place the keyboard in the trunk, a half hour is simply not enough time to be concerned about the electronics and the cold.

But 131 degrees is too high for the silicon junctions AND the plastics.
