Sat navs have been used for a good number of years now and where as previously you had to buy a separate satellite navigation system to use in your car, you can download apps for your phone or tablet which can used to navigate you to your chosen location.

One of the most popular sat nav apps is the one by Google. It is free to use and is often very reliable and up to date. It can show you traffic on your route and divert you a different way if it picks up delays. You can usually change the settings within these apps to avoid toll roads, selected fastest route over shortest and avoid motorways. This allows you to still have control over which way it is going to take you.

With these apps you can also look over the whole route before you set off meaning you will have a rough idea of which direction you will be heading in. It will also tell you how far the journey is, how long it will take you to get there and estimated time of arrival which will update depending on driving speeds. You can even view the route in street view which will allow you to look out for places that you can use as markers for turning or to view where nearby parking is.
