Yeah, dead easy Chris.
Use a proper trim removal tool to save marking the panel, then:
Lever off the cover over the door pull grab, and remove the Torx screw inside the handle.
Removal the second Torx screw at the bottom of the door handle grab.
On the bottom edge of the door - use a 10mm spanner and turn the special fixing through 90° (in the middle of the lower door panel underneath).
Start at the bottom edge and gently but firmly start pulling the door panel away then insert the trim removal tool to "persuade" the pop in fixings to come out (you can be fairly rough and they are quite strong).
After the panel fixings are off, gentle pull the door card slightly backwards to release it from it's front clips and out of the door window channel (just need to jiggle the panel slightly and lift upwards).
Carefully remove the cable to the door release handle (a very simple clip you pull back to release), then carefully release all the wiring connectors - from memory as below:
Drivers door - Windows switch, alarm LED, exterior mirror cable, central locking cable and ambient lighting cable (so 5 in total)
Passenger Door - Windows Switch, ambient lighting only (2 only 2).
On the rears doors it's the same, but the special fixing you need to turn though 90° on the bottom edge of the door is inside the area covered by the dummy red lens on the door. There's also only 3 connectors (apart from the door handle cable) and that's electric windows, tweeter connector and finally a power connector for the door locks etc.
As I'd already done it on the White GTD, I knew what I needed to do so could have the news cards off in a matter of minutes. Hope this helps.
