No one likes getting lost on a journey. It’s especially inconvenient if your job involves driving.

Luckily, navigating is easier than ever before thanks to a range of technology. While many people opt for a smartphone app, we still think a sat nav is the way to go.

To test the theory, we asked one of our Halford Mobile Expert drivers, Rob, to swap his smartphone for the TomTom GO Discover 7” sat nav for one week. How did the sat nav stack up against a smartphone app? Let’s find out…

Did the sat nav make a difference to your day-to-day job?

Rob: The sat nav made a big difference. When I was looking for a destination, it took me to the correct spot, on the correct side of the street, even down to the right house number. This saves a lot of time during the day trying to pinpoint a house.

It also always found faster route calculations when there was congestion, which then decreased journey times.

Were there any other benefits of using a sat nav?

Rob: The larger screen size is a big plus as you can see the upcoming map destinations much easier compared to on a smartphone app.

This really helped when trying to follow the directions while driving to my next destination. I was also able to easily see any traffic alerts and speed cameras that were ahead.

Another great thing is it monitors the speed you’re travelling at against the speed of the road you’re travelling on.

You used the TomTom GO Discover 7” Sat Nav, which features did you find most useful?

Rob: The sat nav comes with lots of different features and most of these were very useful.

While using the sat nav, it picked up any traffic alerts [through the TomTom Traffic Alerts feature] on my route and then diverted me onto a faster route avoiding any potential congestion. When you need to get to a destination on time, this is a big help.

The pin that is dropped at your destination is very accurate and takes you directly to the correct address, not just the street.

It also finds you the appropriate route automatically once inputting your vehicle’s details and it even updates you on the nearest carpark [the TomTom GO Discover 7” comes with one year of parking availability updates].

And would Rob recommend a sat nav to others?

Rob: Yes! This sat nav is a great option thanks to the traffic information, updates and the variety of features it contains. It’s very simple to use and pretty self-explanatory.

It even detects the correct house down to the house number.
