The TomTom XL IQ Routes car satellite navigation system has TomTom’s unique IQ Routes system installed which is designed to save the user time and money. It works by comparing the route planned with thousands of other drivers’ times on the same route, taking into account times of day and even day of the week. Using this data the TomTom XL IQ Routes Europe GPS receiver then gives the user an estimated time of arrival. The TomTom XL IQ Routes car satellite navigation system also features TomTom’s Lane Guidance system which greatly improves driver confidence when crossing between motorways and major road junctions. The TomTom XL IQ Routes Europe GPS receiver will display both 2D and 3D maps. Having external dimensions of 118 mm (4.6 inches) wide by 80 mm (3.1 inches) high by 25 mm (1 inch) deep and weighing only 185 g (6.5 oz), the TomTom XL IQ Routes Europe GPS receiver can be unclipped and conveniently carried in a bag or purse.
