I bought mine in part because it fit the iPhone 6 without needing an adapter. I believe you have to select the proper model for your kind of phone because I don't recall getting any adapters in the package.
Don't bother plugging anything into this unless you don't care what your music sounds like and don't mind the weird occasional bleeps and chirps along with loud static accompanying your tunes.
We don't currently make an adapter to connect Lightning accessories to older iPod models. Fortunately, we make a version of iTrip Auto specifically for those older Apple devices. You can learn more about that product here: http://grff.in/opn0q
