So I just did this, you need the small non cable 30pin to lightning adapter the cable version doesn't transfer audio or video (not that you need video) the mini one has the resistors needed to convert digital signal to analog signal that's why it doesn't work. Newer phones are digital, then your going to want to get a lightning extension as the 30 pin extension is too thick. I recommend these below as I have had success.
Adapter sold at Walmart $20 (sale $18)- This is the apple version too not a knock off.

Extension cable sold on Amazon $15

**This is the cheapest route, I like the cable more than bluetooth which I'm sure works in conjunction with the handsfree, but I just like the cable hard line to stereo a lot better plus it's 1/2 the price and for a broke college kid every saving helps. I extended the 30 pin cable myself with soldering and it's a pretty basic circuit in the housing.**

I'm pretty sure neither of the Apple 30 pin to Lightning adapters will pass video. They are actually identical except for the cable.
