Santa was v. generous this year with a fancy-dan TomTom sat nav. Need some advice as to the best wire to tap into for a switched live. Elektrickery is not my strong point - if i can't see it I struggle, and there's the risk of injury... ( I have the same problem with what my wife's thinking) I had wondered about tapping into the live feed for the accessory socket (behind the socket itself) but damned if I can figure how - if at all- the socket can be removed or pulled forward to access the back of it. Your thorts please folks.
