In the days before SatNav devices for cars were available, I often used to have to prepare for travelling to gigs in strange or unknown locations - particularly in and around London. So I would work out the route with a large-scale map and the London A-Z where necessary and jot down the route changes as a list - and then learn it. I would then have the list on the passenger seat, together with the relevant map, and find my way to the gig. Fast forward to SatNav days. I now check the unknown bits of the route in Google maps - to get an overall perspective of where I'm going - and then dial the route in to my TomTom SatNav device. I also have a road map in the car. Works fine. Belt and braces - and then some more braces...
