I finally got this sorted.
For anyone else attempting it:
You need to feel round the gear gaitor for the clips, and pull the gaitor up and over the gear stick.
If you look down into the centre, you will see two white plastic clips either side of the gearstick - reach under and push each clip out away from the gear stick and lift at the same time. A pair of gloves may help here. I did one side at a time, once the clip is pushed out, the console lifts out.
To disconnect the aux port, some had said the connector was really tight. I used a pair of mole grips (don't grip
too tight!) to press the button in and pulled the connector out no problem. You will then need a flat blade screwdriver to prise the casing out of the centre console.
Once you have all of that out, a dab of solder on each side of the aux port (tw2005, I think you have posted a pic of this previously), and reverse the instructions to get it all back in.
I now have a working aux port, so I can use my bluetooth receiver and Android Auto!!
Thanks for the advice.
