I will be using my Tom Tom Go620 mainly for travel within Spain and Portugal however there will be times when I would travel to many other countries in Europe. Can anyone please tell me if the "Spain and Portugal Map'' is more detailed than the Spain and Portugal maps found within the ''Europe Map''? Similarly, would the separate UK area map be more detailed than the UK maps within the ''Europe Map''?
Many thanks
