I have a 2005 Honda Accord Coupe and I am trying to upgrade the stock radio to the navigation version that came with some of the hybrids. Only problem is I don't have all the wiring harnesses. There were only 3 slots I had to plug in the old OEM stock radio, but in the new navigation one there are 9 slots.. Plus I have the dvd player that comes with it as well and have no idea what to do with it. I don't want to get ripped off at Audio Express and end up paying hundreds for a couple of wires but I have no clue what I exactly need. Does anyone know?
