I just got a g37 and the stereo looks stock but the display is just odd.It doesnt show any of the origanal things the car should. I cant see anything else but that cheap looking options ive attached on the pictures. Anyone knows what this is? Do I have to replace the entire stereo and screen for it to be back to normal?

 

Did you touch the initial setup icon or highlight it to activate it in some way? Seems like it has had a reset somehow but TBH I don't know much about the second gen audio systems.....
