Hey! I just bought a 2006 cobalt ss with a 2.4, it's black and I really like it. It's my first car and I had a single din deck laying around and hated the stock one (cds always got stuck in it, dodnt have aux port etc.)so I bought the things it said to buy on the back of my scosche GM2600f dash kit, it said I needed the $70 interface (GM3000FA) and te antenna adaptor. So I bought it and installed it and everything works really well, besides the fact that I now have two set of dingers, it's really annoying. Is there anything I can do to fix this? Do I need that interface because it could be returned

 

Help would be greatly appreciated, thanks in advance
