I'm thinking I can't go wrong with Pioneer but have never owned or used a double-din with a screen. How do these function in hot and/or cold temperatures? In the summer, it gets hot here and you know how hot a vehicle interior gets in hot temperatures. Scorchin'. And in the winter, it gets so cold, you have to pull your coat sleeves over your hands while driving your car, or you'll frostbite your ****in fingers off on the steering wheel before you make it to work in the morning.
Will these hot and cold temeratures kill the screen?
P.S. ****ing ****in ****er. :)
