Well... for those with a //M, fitting’s a little more complicated than a standard Z, so here goes.
1. Tools for the job, trim removal tool, Phillips screwdriver, double sided sticky tape, tape, bowl for screws & gromets & a hoover
2. Disconnect rear boot light
3. Undo the 4 Phillips screws holding the plastic panel with warning triangle
4. Remove both rear light bulb access covers & remove all parts
5. Remove floor
6. Remove left side black grommet next to light cluster
7. Remove grommet on boot floor holding rear vertical carpet
8. Remove left side trim... there are two internal clips that a trim removal tool makes light work of
9. Twist left carpet & rear carpet & support it anyway u like
10. Mine has a CD Player & removing the connectors was PITA
11. Connect with GROM wiring, using double sided tape to stop them rattling
12. Feed through & tie off at regular intervals to the left side to wheel arch
13. Remove roof sensor thingy & rear rubber boot seal - u do not need to release boot lining (like I did) as is a PITA to put back properly
14. Fit mic per pic & feed to rear
15. I sited the GROM unit about 50cm away from car Ariel, sticking to side of car with double sided tape for unit, excess cable & other bits
16. FIT ALL connectors before sticking to side of car
17. Test your handiwork before reassembly
18. Take your time & make it look like no one was there ;@)
19. Good hunting
