Hi, I m new to this forum and planning to buy a 2008 G37s coupe which I checked yesterday. Everything works well in the car other than the radio. When u turn on the FM radio, there is very low sound even if u volume up all the way. But AM radio and XM radio works well. I searched everywhere but couldn't find whats wrong with it. The dealer also mentioned that they couldn't find it, and will not install new radio which will increase their cost too much. Please help me on this issue.
