MP3 pocket troubles...Help!
 

Sorry mods, I posted this in the electronics section already by mistake.

I recently purchased an MP3 pocket from the dealer for single DIN deck I bought for my P5. It fits into my dash great, but there is some space between the pocket and the deck so it doesn't fit tight enough. I have heard a rumor that there is another piece you need to go in between the deck and the pocket...sort of like a bar or something??? Does anyone know if this is true and if so, how can I get this piece
Any advice is helpful....Thanks!
