Hey, I just installed an avic-d3 into my 2002 kia optima and everything works except I'm not getting any sound out of the speakers. I checked all the connections and looked online and I can't figure out what's wrong. If anyone can help me out here it's much appreciated.

Blue/white wire of avic harness must be connected to the blue or blue/white wire in the hyundai harness for your car.

Thanks for the help man. It works now but the volume is way too loud. I went into the loudness setting and turned it to low but the ping that sounds everytime you hit a button is extremely loud and the only way to get a normal volume on a source is by putting the volume on 1 or 2. If you have any suggestions it'd really help. Thanks for the last tip.
