Hello everyone.. New to this forum.. Just got a 2002 Hyundai Sonata GLS.. As you all know the Radio stinks and gets Error 2 .. blah blah blah.. So i went out and bought a dual hd radio. I got the wire harness and dash kit from ebay. Everywhere I looked had the same wire harness for the 2002 Sonata. Hooked everything up as instructed and the radio turns on, but NO sound from the speakers.. I have double and triple check to make sure everything was hooked up to where it belonged per the radio and per the wire harness.. And still NO SOUND... So im lost.. Anyone have an idea as what to do.. Please help..
