TomTom One V4 Europe 22 Review - TomTom One V4 Europe 22 Review


It also has an excellent POI database, with most petrol stations and many major supermarkets covered, plus there’s TomTom’s excellent Help Me menu, with its quick-fire listings of nearby pharmacies, hospitals, doctors, vets and so on – invaluable if you happen to get into trouble somewhere you don’t know.

Updating the unit is a doddle too, with TomTom’s excellent Home software, and as with the rest of the TomTom range you can make map corrections, upload them to TomTom’s servers and download other users’ map corrections for free – though the One doesn’t make it easy to simply mark locations while driving as the more expensive devices do.

Navigation-wise, however, I was surprised to find that the One is not as strong as previous TomToms I’ve reviewed. The maps are clear – if a little old-fashioned-looking – and that large, clear speaker means that you’ll never miss a voice instruction. Route calculation is swift – a long route from London to Dologellau in Snowdonia, Wales was dispatched in well under 20 seconds. Satellite lock is achieved very quickly too, and in difficult circumstances it performs admirably; it managed to get a position in my kitchen, two feet away from the window and with a very narrow view of the sky above, which bodes well for inner city driving.

But there is a major problem with the One and it centres on a noticeable position lag. What this means is that your position on-screen follows slightly behind your real position on the road. Most of the time it isn’t a problem, but as soon as you approach a few tightly-spaced turnings, or a large roundabout that you need swift instructions on, you’re in trouble.

I frequently took wrong turnings on roundabouts with the One – having forgotten which exit I needed, the on-screen map lagged so far behind my real-life position that it was difficult to know where to get off. To be fair, the One does give you audio instructions well in advance – “Take the third exit at the roundabout”, for instance – but sometimes you’ll forget, and with the roundabout turning icon not particularly helpful it will then be a matter of guesswork as to which way you’re supposed to go.

What this means that, for the first time in ages, I have to say I’m not that impressed with this TomTom. It has European maps, excellent usability and superb physical design, but it just doesn’t do enough in other ways to make it worth spending £150 on.


If you desperately want a TomTom, then buy the (article:TomTom-One-XL-Europe): it is £20 to £30 more but has more solid performance, a bigger screen and that makes it a better buy. Currently, The One is simply too expensive, doesn’t quite pack enough features in and can’t quite match the performance of its larger siblings.
