The test routes I generated were the ones that I would normally take-a good sign. And even without a live traffic receiver, its travel-time estimates are pretty accurate. The XXL 540S takes such variability into account in generating recommended routes. For example, a trip from New Jersey to Manhattan takes longer during weekday rush-hour traffic than on a weekend or at midday.
Like most TomTom products, the XXL 540S comes with IQ Routes, which can calculate routes and estimate times of arrival based on historical traffic data rather than on speed limits.
