I bought a used 2007 Acura MDX from dealership recently. I made the mistake and rushed without doing a through check. I saw that it had a DVD console so I assumed I had the tech trim. I later realized when I couldn't find the audio buttons for the DVD player that it was a aftermarket that the previous owner installed on the base level trim of the MDX. So I'm stuck with this DVD player (a whole set of new children DVDs) and no sound. Any suggestions where I could hear the player. The video works fine just no sound.
