I have a 2007 Renault Master (57 plate) and I am having trouble with the cigar socket which I use to charge my Mio A201 Sat Nav and to power (via a cable take-off at the rear) my reversing camera. The other day the socket went dead so (naturally) I decided to look at the fuses. I found the box OK, well hidden and almost inaccessible under dashboard near driver's knees. I checked the obvious fuse (cigar lighter) and some other fully intending to check then all by taking them out and checking for broken links. I gave up after a while due to the difficulty I found getting them back into the box. The photo below shows the layout of the fuses with the cigar lighter third from the top on the left hand side. This fuse is unbroken so I am at a loss. Any ideas?
