I got the following: Wiring kit.
From memory I only bought the harness & patch lead from these people, the facia adapter was a Scoche one off ebay for about £12. I don't see the DAB aerial in your kit, usually about £15-20. You'll need to select 'powered antennae' from the Pioneer unit during set up, from memory. I don't remember if there's any factory phono connections as it was about 18 months ago when I did mine. You won't need to use the extra metal cage, but you will need to use the factory Bose head unit brackets on the side. I found I had to cut a small piece off each of them at the bottom to get them to fit.
If you're not too familiar with fitting a stereo it can all seem a bit daunting, but there's plenty of guides around that should help you.
