Is there anyway I can hook my Navman Pocket PiN to my factory F150 6 disc CD player? I have a 1 gig card and want to play all of my MP3's through the factory unit.

It has headphone port for hook up. Any one have any ideas or do we have a left and right audio port on the back of the raidio? It is not the upgraded one but just the standard Lariat 6 Disc indash radio.

Thanks guys!
