Yes it's a hybrid tuner but as most of the uk's analogue signal has been switched off now I couldn't tell you if it still works. Went camping in July south coast of England cracking picture, missus sat in the car and watched the Grand Prix. Had the tv in motion unlocked "thanks again Jas" and it worked most of the way home.
As for how I did it, I got a hybrid tuner from a facelift E53 from a breakers and simple as 1 out 1 in, hardest part was getting the modules out and back in to the plastic frame they sit in.
