Just bought a car it has a 10disc changer in the trunk, the display inside works, changes cds/tracks but I can't figure out how to switch the stereo from radio to aux/cd changer, the aux button does completely nothing.

why would any car have a cd changer in the trunk... anyways its probably a broken button

Har har...its a 95 cutlass the cd changer is in the trunk what the fuck...wanna carry a 10disc cd changer in your passenger seat?

It could be the button...but the chances...

the chances a button is broken on a 16 year old head unit is pretty high...

Bah ok fuck it, I should go buy a new device anyways, thanks.
