Summer Survival Guide - Part 2 - No sat-nav?

You don't necessarily have to invest in dedicated satellite-navigation.

With a suitable mobile phone, you can buy software to turn it into a miniature sat-nav unit.

Garmin, Mio and TomTom all produce suitable kit, costing from £50.

Key mobile phone service providers such as Orange and O2 offer phone subscription packages that include sat-nav.

Alternatively, you could opt for a specific telephone, which includes GPS mapping, backed by voice navigation.

Bear in mind, though, that their screens won't necessarily be as easy to view as those on dedicated sat-nav kit.

Equally, your passenger could use a mobile to browse traffic-related websites, and there's nothing to stop you looking up similar information at home before you leave.

And, of course, the good old map book still has its place, even if it can't rival more 'real-time' solutions for accurate information on accidents, traffic black spots or speed cameras.

Choose a spiral-bound book, such as the AA's Road Atlas Britain (£15), that will fit in a glovebox.

Or, for the same money, there are larger, bigger-scale designs such as Collins' Superscale Britain 2007.
