What exactly is smart2go? smart2go is a freeware for your mobile phone for downloading maps and street plans, and also for saving your favourite spots to then share them with your friends. But that’s not all: Explore the world with our optional, premium-brand travel guides, packed with valuable information and important tips. And our optional navigation upgrade brings you professional navigation with GPS. Do I have to have a GPS receiver? No, smart2go can do a lot even without a GPS receiver: high-resolution maps and street plans for countries all round the world, full of interesting locations such as restaurants, clubs and cafés; route planning; city guides (optional) and lots more besides. But to harness the full potential of smart2go (for instance, turn-by-turn navigation with voice guidance), you will need a GPS receiver. Some mobile devices already have a receiver integrated in them, but it is also easy to connect an external GPS receiver to your mobile phone using Bluetooth.
