Hi, ich hab die gleiche Mittelarmlehne nachgerüstet (also die originale, nicht die Nachrüstlösung!) und mir hat diese Anleitung aus dem englischen Mini-Forum sehr geholfen:

1. Remove the torx screw from the rear cup holder and also the front 2 cup holders (3 in total);
2. Unclip the cover/boot around the handbrake (This was the most diffcult stage in the whole process, but we found it easier to start on the sides and then work your way around);
3. Grab the long plastic cover that runs from the from the rear cupholder to the front cupholders and lightlypull the sides apart near the handbrake - you'll hear the cover clip off ever-so-lightly;
4. Feed loose handbrake cover/boot through the plastic cover, as you remove it - PLEASE NOTE: Right next to the handbrake, you'll see a thin yellow and blue wire that is connected to the underside of the long plastic cover - Use a pair of pliers to unclip the plastic clip that holds it in place (it easily snaps out);
5. Twist cover (as the cigarette lighter wire is stilled joined) parallel to the dashboard;
6. Remove the 3 torx nuts from the old base plate that is now exposed and remove it over the handbrake;
7. Insert supplied foam padding over the silver module in front of the handbrake (it is the one that carries the airbag warning on it);
8. Insert the new, longer base plate and reattach using the same 3 torx nuts that were removed in step 6;
9. Insert armrest into the base plate and secure with 3 torx screws (supplied in retro fit kit) - REMEMBER to reattach the plastic clip that holds the yellow and blue wire in place into the bottom of the base plate;
10. Reinstall the long plastic cover that runs from the front cupholders to the rear cupholder - make sure you hear it clip into place on each side of the handbrake - Reinstall the 2 torx screws that were removed in step 1 for the front cupholders;
11. Install new rear cupholder and the 1 torx screw removed in step 1;
12. Install the 2 rear covers to the base of the armrest - they go in the small gap between the base of the armrest and the base of the rear seat. The 2 covers interlock with each other in the middle and each have a torx screw that is attached on the side of each (2 torx screws in total);
13. Insert tray into armrest;
14. Clip on the rear small cover at the back of the tray;
15. Clip on the sliding lid;
16. And your done!
