I honestly can't imagine how I used to survive with sat nav, hours of driving round in circles has been replaced by "quickest route" and "shortest route". You just type in your destination and away you go - this one even has voice recognition so you just tell it where you want to go. Tomtom now has a map update feature, so your satnav isn't out of date for long as it now will update speed limits, one way streets and new roads thanks to the network of users using it. Not only is it really helpful, but it replaces the annual purchase of map updates which would cost around £40 a time.
