Australia is a very big country and things were very different before GPS came along. Whether you were taking a trip down the coast or a drive through the mountains, you had to plan ahead and that usually involved digging through your map guide or road atlas. Often supplied by what was once called the RTA, then the RMS and now, simply Service NSW, you would spend the morning thumbing your way through one of these massive tomes, doing your best to memorise street names and landmarks for turns. It often would be filled with post-it notes, book marking your trips and yet you still might find yourself getting lost. Nowadays, the post-it notes and three kilo books have become a thing of the past and we find ourselves guided through the streets of Australia by good ol’ Karen Jacobson - our Australian GPS voice. Of course, in most modern cars, GPS and expansive infotainment systems are virtually guaranteed but, if you’ve got an older vehicle, a classic car or even a stripped back work van, GPS isn’t always included.
