Thanks for your help. was so easy.
Will just add a few pointers I found.
- Taking the rubber door surround off along the A pillars, makes removing the trim much easier.
- DAsh dose not need to be removed, just lifted at the front to allow access to the bolt
- Unclipping the Vents from the surround (its just 2 plastic loop clips) and popping them back in the vent hole, makes removal a lot easier.
- The indicator stalk can get in the way. Move the steering wheel column up/down, you can get passed this annoying obstacle
- The top bracket, for the 10mm bolt, may catch on the inside of dash. It is tight, but if you rotate the front of the unit upwards as you slide out it will come free.
- Mind the cables. It a tight hole to extract the unit from. don't force anything. last thing you need is to be redoing the connectors or wiring harness. ( no I didn't damage mine )
Another Hint, If you have any annoying cables (like dash cam / satnav) running up the side of the A pillar. Use this moment to hide them behind the trim.
