I have a pending mod for this specific part...forgot to do it when they were working on my roof. Going to be a DIY, can anyone offer any step-by-step instructions on how I can pop this puppy off for the mod?
Not much help Alwin, but I presume you're going to re-attach it after your mod. I would think the wiring into this aerial will be pretty complex as it houses the radio, Satnav, phone, and TV aerials all in one. Not going to be easy...
drop the headlining at the rear only then remove the c pillar trims around the rear window and disconnect the two coax connections and remove the 21mm nut.Be carefull when lowering the roof lining as they crease.If you wish to remove the lining complete you will have to remove the windscreen.Good luck and it can be done as i have replaced gps aerial as described
