Hi, I've just collected a C-Tourer 149 and want to access the HDMI and USB socket on the side of the tv. The tv is mounted behind the small jump seat and pulls up to view. It moves towards the front of the motorhome but I can't see a way of releasing the left hand side (as you look at it) from the mounting bracket so I can access the HDMI and USB sockets easily. There appears to be a cut-out in the bracket and a small rod on the swinging part of the arm which looks like it should release the TV but the rod is too long to fit the cut-out and it doesn't push up or pull out. Any idea how to get the tv further out so I can get at the sockets?
