I'm looking for a replacement in my 05 cobalt LS I want one of those navigation touch screens with the ipod hookup.. I saw one on eBay for about $550 but I wanted to see if anyone was selling one by any chance or if they're sold elsewhere cheaper

 

There is no such thing as a stock navigation touch screen for our cars and def not for a 05. The only way you can get all that is to get an aftermarked set up. I hade a Pioneer Avic and loved it. Much better than what stock would be anyways. And you would prob be spending around $500 for it all and that's on the cheaper side.
