I have heard that the HUD displays both a RPM gauge and a shift light. I can't see either in or outside of RS modes. I'm still breaking in the car so I understand why I haven't seen the shift light, but what am I doing wrong with the RPM gauge? I do see a thin grey line above gear and speed while in RS modes but it doesn't do anything. Any help would be appreciated, thanks.
