hi my car doesn't play any cd!! what can be the problem?? or what can i do?? do i need to reset it?? help lease!!

 

Whenever I try to use my cd player, it plays for about 30 seconds and then it just... stops. At first I thought it was the cd but it ha pens on every cd I have. I tried cleaning the lens and everything. I even opened it up to see if the lens isn't aligned right but it is.

 

My cd player stopped paying cd's also. I was still under the factory warranty so they replaced the unit.

 

I honestly don't think I've fed my car a single CD. Now I want to go check it.
