The audio on my wife's 2017 Energi just stopped working, it show's OFF on the screen and will not turn on when the on/off button is pushed. Any ideas where to look to fix this? She does have a appointment with the dealer for Friday, just trying to save her the visit. Also the MFM is not working, I remember reading that a fuse (10 or 11) can be pulled to reset, is this correct? Thanks
