2008 Explorer Stock Radio with SYNC

[KP416]

So I just purchased a used 2008 Explorer that supposedly had SYNC. We noticed that the button on the right side of the steering wheel were not working hence I could not use the SYNC option. Since the car is still under warranty I was told it can be repaired by the dealership. After taking it tot he dealership it appears that it is not the stock radio that cam with it and the new radio is not setup for SYNC.

While I deal with the dealership to fix this problem does anyone know where I can find a used 2008 Stock radio with SYNC for an Explorer?

Thanks!
