Look at the stereo option list on Porsche China site. CDR, PCM and Sound package plus (anyone know what that is?) are all options. I didn't take any of those options. Does my GT3 still come with stereo system (usb port/aux in)? Am I missing the touchscreen too?

 

I believe it still comes with a basic 4 x25 w system. When I read my print out after I placed my build, the standard options listed the touchscreen (no nav) and 4 speaker system
