CHRISTMAS is coming and sat nav manufacturers are scrambling to get their new devices in stores ready for the big day.

Market leader TomTom has a new GO range with higher resolution screens.

Simply zoom in and out to find and explore places on the map with your fingertips, then tap on the map to get an instant route to a destination. The new GO series comes with lifetime TomTom Traffic, pinpointing exactly where delays start and end, helping you get to your destination faster.

You connect to this service either via your smartphone or, with the GO 5000 and 6000, straight out the box.

You can also download a new map four times a year, free of charge. Prices start at £159.99 for the TomTom GO 400 and they are available from Halfords, Curry’s and all major electrical stores.
