i GOT IT OFF OF EBAY IT DIDN'T SAY WHICH UNIT IT WAS.

I installed An Navigation radio into my 2004 buick rainier, It was locked so I took it to the dealer to get it unlocked, they tried to program it, but they said it wasn't able to program it, it shows a display for the AM and FM Bands and the other displays, but there is no sound from it, I don't have option for Y91 or Y92. Is there something I can do to get sound from it. or add something. assistance needed.
