for years i have used sat navs going back to 1998 when garmins pointed you in the right direction but no instructions... for phone users ie android, and no doubt apple Tom Tom have finally made an app that works properly.... £15 a year gets you mapping of all Europe plus up dates plus live services...have been using it daily for over a month now and it is better than the co pilot app i have been using for the past couple of years, although co pilot does do RV vehicles which is an extra help for when towing.... neither of these products should be compared to the inferior freebies that are in abundance in app stores. sometimes it difficult to explain why somethings are better but i suppose its a .bit like comparing a Ford Anglia to a Ford Focus... even if the ford Anglia is reliable, its hardly in the same league for anything as a Ford Focus...
