I have a 2006 g6 gt with the stock monsoon audio system like everyone else.. I bought an item called an iSimple that got installed and it went out after about 2 months so I got a new one and it recently did the same thing. Now I am looking to replace the radio for one with a USB or aux input. I know one of my options is to get an 09 version of the same exact unit, but what are my other options? Thanks for your help!
