I hooked up a audiovox all in one dvd console last night in my wife's Yukon.

I bought it used, it didn't come with a remote or wireless headphone. It is in great condition and has a great picture.

BUT........ I have NO SOUND.


I pushed the FM button and it say FM CH.5 89.9. I tuned the radio to the station and nothing.

but I can figure out how the change the station....

I looked the unit up and it says it has a wireless FM module.

Any Idea's on what it could be?

Do I need the remote???

Thanks
