I was experiencing some similar problems... If I left my player plugged all the way into the dash it would not boot after leaving it for a while (30 min or more). The software would lock up as it was loading the database. I figured out that if I pull the unit out (about an inch) before leaving the car, & push it back in before I turn the car on, everything works fine. I don't know if my initial problem still exists because I always pull the player out now.
