USB port not working - Nissan Forum | Nissan Forums forumsclub››Infiniti M37, M56 and Q70 ForumMay 29, 2017I had an old iPod touch I kept my music collection on, in the center console, connected with USB. It stopped working the other day and I noticed the USB cord was freyed so I thought it may have shorted out a fuse. The port will not charge anything or connect to the head unit. I think I have checked every fuse and can't find any that are fried.

You can even control the functions through the audio system or touch-screen monitor (if so equipped).
