The TomTom GO 5100 Sat Nav has a 5 inch multi-touch screen and has an integrated sim meaning it is always connected. It's a step up from the older TomTom Go 5000 model. Features include lifetime World-wide map updates, voice control, lifetime speed camera updates, advanced lane guidance, and quick search. This has now been superseded by the TomTom Go 5200 model, which offers WiFi and world maps.
