I offered 3 potential solutions that work across ever model (unlisted) and you guys are downvoting?
- USB - apple 30 pin: note that the pin number might change depending on release year. Someone smarter than me will mention why firmware might not work out.
- USB to aux: this will give you a headphone jack and is the most reliable
- FM transmitter: if you lack a headphone jack you can also get an FM transmitter. It makes your device a mini radio station. These are pretty unreliable or staticy, but sometimes you need an option. I would recommend a new player first.
