TACHO INFORMATION

When going on a trip from ,say Dublin to Milan,parking overnight in GB,F,I,F,GB.Two questions
(a)do I leave the digicard in the head,from start of journey, i.e. Dublin,to finish journey Dublin,and
(b)do I record each"overnight" stop on the head as GB,F,I,F,GB.(in other words,do I record each territory I stop in?)

(a) - Up to you, doesn’t matter either way but leaving it in is easiest.
(b) - Yes, enter end country as the country you finish each shift in.

Thank you most kindly sir.
