So, I have had my D3 for about 3 weeks now, and last week for the first time the screen did not turn on when I turned the truck on, but the music kept playing. it has happened 3 more times since. i can get in my truck several times a day, but when I go to go home, i turn the truck on, hear music, but the screen is off. I have to turn the truck off and back on again to get the screen to work. sometimes, i have to turn the key off and on several times before it will work. I am probably going to exchange it next week, but I wanted to see if this was a common problem first.
