So, a few piccies with a little bit of a write up. Haven't taken any photos of laying the cable or feeding it under the trim (as I guess you know how to do that), but have taken a few photos to show the bits you probably haven't seen.
Likewise, haven't taken any photos of the piggy back fuses, as Roy has done such a great job above!!
So, after taking the original headrest out, you need to remove the seat back so you can start to work. Each seat back is held on by 3 clips that it you forcefully remove, will need to be replaced. To re-use the clips, grab the top of the seat back and move sharply to the right:
Once you've done that the seat back will fall towards you and you can see the 3 retaining clips:
You'll need to take the back off completely, and to do so you need to pull it upwards to clear the two retaining clips in the next photo. No need for full removal of the material at the bottom as you can just rest the back to you as you're working:
Next, you need to feed the cable through the poles from the headrests. HOWEVER, the poles that come with the DVD headrests are 10mm wide and the poles for our seats are 14mm wide. You can get 14mm poles to use, but they are used as skins as opposed to replacements and so are not a tight fit and rattle around. I've overcome that by using some Material harness (Tesa) tape to stop the rattle:
Next is to put the new poles in, ready to feed the cable through, and put the headrests in place. You'll see I've taped the antenna and power cables together for ease of threading through
Then feed the cable through all the way and pull it through
The only downside of these DVD players is the large amount of cabling they come with to connect external sources. Once you've wired up the +ve and earth cables, you're left with this:
I bound it all together using insulation tape and then a covering of Tesa tape to stop any rattles.
Next is to put the seat back together and the three clips I mentioned before. So in reverse order, make sure the two retaining clips at the bottom are lifted back over the anchor on the seat. Then you need to deal with the top clips. The way I did it was this. I got a pair of pliers to pull them out slightly to the same length:
You then have to line up all three clips to the anchor point on the seat back, and slide them back in. I did this using my fingers as there is just enough clearance between the seat and the back:
Once all three have slid into their anchor points, push them back fiercely for 3 satisfying pops!!
Last job is to test the DVD players and away you go!!
Hope it's of some use.
