checking out a streetview app beforehand is another option and makes it a bit easier to memorise things. instead of having to remember '2nd left, 3rd right, 1st left' you only have to remember the landmarks at each turn and then the instructions become 'left, right, left'

another thing ive done a few times for long journeys is to write down on paper a list of the road numbers and then beside each number write the distance that needs to be travelled on that road. just do the route in an app before you leave and copy the details from that. having only the list to work off definitely forces you to keep your brain more active
