The TomTom GO x50 LIVE series has debuted with a range of three satnav devices housing more maps, more options and more services to spend £7.99 per month on than the last time at IFA in Berlin, Germany.

The GO 950, 750 and 550 offer fully customisable interfaces with the routes calculated by the IQ system which bases its suggestions on the historical metrics of road speeds from millions of drivers however look identical from the outside.

The devices have new menus for calculating eco-friendly routes and improving on frequently travelled journeys. The 950 comes with EPT for uninterrupted navigation when driving through tunnels and both it and the 750 have pre-installed maps of 45 countries. The 550 has just the UK and Republic of Ireland.

The series comes out this autumn.
