Hey guys, recently hooked up a N3 to my 2005 Jeep Liberty. Powers on, screen rotates as normal, Ipod hook up works, cd player works. Just having problems of getting the audio to come on. I hear the beeps in the speakers when scrolling through soundtracks or the ring tone when you hit the navigation button. Everything works as it should, just don't have any audio when playing CD's, Ipod, or Radio. Had the unit tested and the cd player itself tested out fine. Could it be the Brain Data Cable or the Brain itself? Would the rest be working like it does with a faulty brain? Any input would be appreciated. Thanks.

scroll in the audio menu and see so you dont have the mute on
