Majority of cars now have satnav
2014 saw the number of cars in UK with satnav outnumbering those without for the first time.
Percentages of cars with integrated systems, hand-held/plug-in systems and no satnav over the past years are given as:
2009 - 6, 27, 68 %
2010 - 6, 32, 61 %
2011 - 7, 33, 59 %
2012 - 9, 37, 54 %
2013 - 11, 37, 52 %
2014 - 13, 39, 48 %
So 2014 was the year that more cars with satnav guidance than without were driven on UK roads.
The figures are published, along with many others, in the Department for Transport's 'National Travel Survey: 2014'. It is fascinating reading and can be downloaded from the links below . .
