My cigarette lighter isn't working for my sat nav to actually work on the road, I've pulled down the fuse box thing at the drivers side but cant make sense of what fuse I actually need to go buy. Can someone please help me?

20amp, there is only 2 and think 1 is for the horn

Might not be the fuse

The Punto has a Stupid European Cigarette lighter socket

Most sat Navs use a japan/Chinese Plug which is like 2mm Smaller

So Most devices dont fit the Socket very well - I personally got around the problem by using a Ring 2 way splitter

The Splitter has a Collar which is optional to have on to allow the plug to fit snug in the socket
Mine lives in the car and never comes out
means i have 2 sockets - and everything fits Snug
