Hello I'm new here registered last week when I bought an Avic x930bt from a friend wired it all up works great but one small problem when you first start the car the TV turns on the buttons on the left light up then fade away they do not stay on I've tried everything and nothing seems to work one thing that is wrong with the TV unit is the CD player wont feed any CDs like as if the mechanism is broken any help on this topic is greatly appreciated, thank you.
