I am installing a Pioneer cd player into my sisters 97 pathfinder, I wired up everything per the instructions and the unit turns on, but there is no audio. I checked the fuse for the player and it is good. And when I put the factory unit back in it worked fine sound and all. Is this a defective unit or is there a bigger problem? any advice from someone who has experience with this car would be much appreciated? Thanks in Advance!

 

Problem solved, thanks for all the awsome posts to help me out guys!
