iPod no longer connecting to the car
My iPod touch has stopped connecting to the car. It says it does not support this accessory, the car says no audio files. It has been fine for months. I have reset and restarted the iPod. I've tried my iPad with the car and that's still fine so it must be the iPod rather than the car. I started it playing an audio book this morning it it wasn't in the right place in the chapter so I unplugged it to alter the chapter position, when I reconnected it, it just wouldn't do anything. Any help would be gratefully received. Thank you.
iPod touch (4th generation)
