Driving with TomTom IQ Routes ensures users automatically have the most reliable travel and arrival times on their device. Depending on the time of the week or hour of the day drivers plan to set off, the most efficient route will be calculated for that particular moment. It takes into account any factors that can affect or delay drivers' journeys based on facts derived from years of gathering anonymous historic speed measurements. TomTom's advanced lane guidance feature makes navigating difficult or complex junctions, or crossing multiple lanes, easier and safer. It gives drivers timely vocal instructions and clearly indicates which lane or exit to take on the screen of the device, and provides a clear view of the road layout ahead.
