Using “free” navigation abroad could cost over *20p per mile in roaming charges 185 mile Calais to Paris trip costs *£24 to £39 in roaming charges one way, *£52 to £78 return journey Garmin, global leaders in satellite navigation**, today revealed the cost of using “free” satellite navigation on your mobile phone abroad. Users can rack up a phone bill more expensive than the cost of their fuel used for the journey. The company found that using one of the most well known turn-by-turn navigation services on a mobile phone generated a bill of £36 in data roaming charges for a journey from Calais to Paris – some 185 miles – meaning a cost for navigation alone of over 20 pence per mile. Garmin’s Head of Communications, Anthony Chmarny said: “Using free satellite navigation isn’t as free as it would like to make out, especially when you are using your mobile phone abroad. Many of the well known navigation products use the mobile phone network to download maps as they go, meaning people could end up with a nasty shock when their mobile phone bills arrive – the costs could be double that of the fuel used for the journey they were navigating. “We tested the route from Calais to Paris four times and each time it came up with the same results: between 12-13 megabytes of data per journey. On a pay as you go mobile phone this meant £36 to £39 to get from Calais to Paris – some 185 miles on a contract plan the cost is a little less, but still equates to £24 to £26 per single journey.” More
