Yup, as others have said.. and the good news is that should you get an Oyster sat system fitted that plate just saved you about £50 !!
I made my own because I was not willing to pay that sort of dosh for £12 ( retail ! ) of ally and four holes !!
Well the large plate is in line with the door and there's nothing to see inside. The schaudt 220 control panel is above the door.
The small plate is over the garage with cabling going down to the bottom of the garage to a grey box.
I have seen some old threads where it's mentioned that the Adrias come prewired for solar/satellite & reversing camera. We've found part of the reversing camera cable, as it's labelled (dunno where the other end is, assuming it comes out of the electro bloc both sides???)
So are the two plates connected? Numpty question - if there was a dish does that mean that there was a cable running along the roof down to the small plate and into the van?
The rest of the sat system ( a thick wire, a gland for entry and the sat system control box('s) will all be removed.
If done well there would be no sign left inside the van.. Usually even the entry point is made good.
