What I was thinking of doing was bringing the wire up through the left tweeter hole and behind the angle trim I'm talking about, going all the way up, then coming across underneath/above the ceiling fabric and then fixing it half way along, with the ground tag sticking to the metal frame under the fabric, the box might also fit under there too, then the actual aerial would just be the tiny bit of stick on film onto the windscreen. I don't think anyone would notice it at all since it would be in the same area as the rear view mirror. But I tried to take the passenger side lower dash off this morning and failed, why do they make these things so hard to take apart! I found it was joined to the centre lower dash and that would all have to come off before I could get the passenger lower dash off. What a nightmare! I've currently got the aerial wound up in the small cubby hole under the single DIN stereo, so will leave it there for a while. Works ok where I live, probably won't work great when I'm on the road. Pete: The only way I can see of mounting it on the rear passenger windows would be to bring it up the B pillar, but I can't see anywhere to hide it their either? Not sure I understood you.
