i was driving home from VA (7 hour drive) and on the way, my volume button wasn't working on my Kenwood DPX 4020...car been on all day (wish i had a cold air intake at times like this) but anyway, nothing was working and when i put my hand on the screen, it was hot as all hizell...volume blasting and i couldn't turn it down...had to cut the car off and put it back on...then it started working....car was on all day and stereo was hot...i was scared that i broke my baby but it's working fine now...have any of you had this problem with your aftermarket stereos? although i doubt any of you drive 7 hours on a daily basis to realize this
