TomTom One Regional Assist review
The One is TomTom's cheapest satnav. It has a 3½in screen and comes with just UK and Ireland maps as standard, although a version with 22 European countries costs £20 more.
Instead of slipping the unit into a cradle, the suction cup comes attached. However, it can also make the One harder to position on your windscreen. Despite its budget orientation, the One has many of the features of its higher-end siblings. The map view makes the most of the screen area, with just the lower quarter given over to an information strip telling you useful things such as current time and speed, plus distance to destination. The left-hand side shows the next turning.
A safety camera database comes preloaded, with a year's subscription to updates costing a reasonable £20. TomTom's MapShare system, which is a wiki-style user-generated map and updating service, is also supported. Users can upload their amendments and download those of others. The POI database includes icons for petrol stations, restaurants, hotels and parking; there's also a full list of all categories available.
However, a few welcome features available in TomTom's higher-end devices are missing here. For example, instead of sensing light conditions and adjusting its display accordingly, as with the GO range, the One uses time of day. It has no Bluetooth receiver for mobile phone connectivity, either. It doesn't have traffic updates built in, although an RDS-TMC receiver can be added for £49. This also allows you to get weather reports and update safety camera information on the fly.
TomTom's One Regional Assist is keenly priced and a good choice if you're on a budget. It even comes with a free year of roadside assistance from Mondial Assistance, worth around £30. However, Navigon's 1210 provides full European maps for just £5 more, and Navman's S30 3D has similar features to the One for around £20 less.
