With thanks/apologies to Stu for the A) help/advice the steal of some of his piccies from BlueTooth instructions - as I didn't take step by step pics during actual install.

Step 1) Remove A pillar trim

If you have curtain AIRBAGs (RED line in pics) you will need to prize out plastic AIRBAG label with small flat blade/screw driver and undo Torx screw underneath (T20) before the next step.

For non-airbag it just pulls off. Start from the top and work your way down behind the trim to release the clips using just your fingers (there are four clips).

Step 2) Lay in wiring

Using a flat blade screw driver or the key blade prize off fuse box cover at dash end.

Temporarily sucker RA to windscreen where it is to be installed.

Lay in USB power line from the top down. I taped the wire in the corner of A-pillar AWAY from airbag and used a cable tie where possible (if you have a curtain airbag many of the A-pillar holes are used to secure the airbag).

Poke/feed through to dash/fuse box.

Step 3) Remove lower knee panel on driver's side

Remove the headlight switch, this is done by pushing the kn0b in at the same time as turning to the sidelights position, withdraw the switch and disconnect the plug.

Using trim removal tool or similar flat blade carefully prise off ally look trim either side of steering wheel to reveal two of the five knee panel securing screws.

Unscrew the five Torx screws (T20) securing knee pannel.

Carefully hinge downwards as diagnostics port still attached.

Step 4) Remove fuse box

Unscrew the two Torx screws holding fuse box on.

Unclip back lid.

Unlock purple retaining matrix by pressing the small black clip to release. The purple matrix can now slide 2mm to allow terminal access.

Add new fuse blade terminal (000 979 227) - I used IGN switch fuseway 41 with a 3A blade fuse (purple).

Push in wire and re-lock purple matrix. Clip backing lid on.

Add a ring tongue earthing tag to one of the fuse box mountings and reinstall fuse box.

Step 5) Securing 12v/5v converter (hacked cigar adapter)

Solder on new 12v and 0v lines to converter and secure on metal dash frame.

Connect up USB power line to adapter. Test RA.

Coil up any spare USB power line and secure.

Step 6) Reassemble all the bits you have left and final fix RA position on window.

My you have been a busy boy Paul.

Yeah - instructions sound like 10 minute max - must have faffed and apprehensively pushed/pulled things for the best part of 2 hours to get it done:O

I did solder/heatshrink and tape and cable tie in a completely over-engineered manner - that RA aint coming out now!
