I have all the buttons to indicate that i have a six disc changer (disc up/down etc.) but none of them work, does this mean I have it, its just not working, or do all the cd players in our cars have this on them? Thanks in advance and sorry for such a newbie question

 

are you trying to change discs in the car? or are you trying to add more into the car?

 

All the OEM stereos have those buttons. If you have anything other than the single CD player installed, you'll have a special graphic above the "1" button on the piano black panel (see photo of an OEM MP3 CD player). The CD changer has a graphic of multiple CD's stacked together.

 

Aw man, I thought it was only single but I was hoping it was six disc not working because its still on factory warranty and I could've got it replaced. I know it's been asked before somewhere, but while on the topic of six disc, can I swap this one out for a six disc without any trouble?
