Iu 201s for iphone 4 was for appmode for dvd units. For 5s u need to upgrade to the new firmware which has iphone 5/5s support for appmode. But since yours in 1din, you will be able to use the simple lightening cable for digital playback. But I think firmware update is mandatory to support 5s.
EDIT: Just checked in friends car, the lightening cable works fine without any update.
