Last week i installed for same reasons( GPS)a cigarette lighter on my 4/4 78...i did buy the housing at an auto parts shop and installed this beneath the dasch. aside from the heat compartement using a piece of aluminium sheet, using ground wire from the heater housing where i attached the alluminium sheet with parker screws and using a positive + wire attached to a heavy brown wire wich got a fuse on it, so it is now protected by this fuse...check out wich way the current flows so you do attache the wire at the right place...i do not have a elctrical sheme but it works just fine for me now...
re copy/ sattnav connection does not work: i do have this same problem on my lotus and on the morgan cigarette connection, it works just fine by using the foldable extention kit to plug in, on this extention plug there is even a small green light that indicates the working or not working mode...(garmin) it must be the original male plug that does not work on every cigarette lighter housing.
