Do you have standard Media System Colour (5"), Media System Plus (5.8") or Sat Nav?
Judging by your description (one USB and Aux only in glove box) you have Media System Colour, which does NOT support anything else, than USB storage devices. So you'll not be able to connect iPhone or any other device, that does not work as simple USB storage (FAT32 formated). Android phones based on KitKat will also not work, as those are using MTP protocol.
So if you in fact have 5" media system, don't bother with any cables, as it's just waste of money - it will just not work.
Instead get SD card. It's better than USB stick, as with sticks it sometimes happens, that media system freezes. It does not happen with SD.
