I guess this can be answered easily with a DMM. Just put it to CD and put the + on the amp turn on wire and ground the meter on the other side. If there is +12V at this point then the CD section is gone for sure.
Doing due diligence checks never killed a person.
In this case, if that is the problem it can easily and cheaply be remedied verse buying another HU. Especially if Tim has to refund the guy...

good points. considering I sold the head unit to him probably 6 months ago, which really wasnt a sell, because he traded me head units and ended up getting the one he traded me back...really long story. I guess I more or less gave it to him..

yeah, cause just the CD section doesnt work. The Head unit powers up and he can get the tuner section to come on, in fact he was listening to the radio when I got to his house.

Im thinking the CD section has crapped out on him.

At this point in the game there is NO harm in trying this.

If by chance it DOES work then he just needs to provide a switched 12V source as his amp turn on lead.

Its an odd situation really...

As I stated way earlier, try jumping the remote turn (amplifier side) with a known 12V source just to SEE if it works.
But it is working with the radio,its just the cd wont play. Throw it in the nearest garbage can and get another.

Well dudes, I went and checked it out personally. He does indeed have it all wired correctly. I was incorrect on one issue though, the unit does not support ipod. So no he has no ipod. But yes he does have radio in all speakers.

The only option I am at at this point is that like everyone else the CD section has went kapoot.

On a side note he told me that one of his buddies that he works with, why I have no good explanation or even a good lie to tell for why he did this, but he hooked the ground up to the remote wire.
Would that or could that have fried just one section of the unit?? or would it have fried the whole thing, or did nothing at all??

Im gonna guess the CD section is bad like everyone else.
