Elsewhere, it has a surprisingly comprehensive feature set for its £100 price. Though there's no Bluetooth for hands-free operation, you do get a TMC receiver built in - it's an elegant solution, too, with the aerial integrated into the lighter socket power cable so no need to have wires draped in an unsightly manner around the edge of your windscreen. The downside is that in order to access TMC traffic information you have to pay an extra £40, upping the price by a whopping 40%.
More impressively, you get speed camera warnings installed as standard. It took me a while to figure out that you have to delve into the menu settings and read a disclaimer notice before the option becomes available, but it's still an unusual inclusion in a sat-nav this cheap.
Plus, there's text-to-speech for numbered roads and motorways, and the 2100 also has the excellent Navigon mapping engine and route-planning tools of its bigger brother. The maps are clean and extremely clear: your route is marked in bright orange over grey, with realistic - rather than simply conceptual - next-turn icons displayed on the left. POIs such as petrol stations and restaurants are indicated with brightly-coloured, occasionally-branded POI icons. Voice instructions are delivered in timely fashion and, with traditional Navigon politeness - a "please" is always inserted before "turn left" or "make a U-turn".
The next-turn icons are particularly good. Not only do they seem to provide an accurate overhead view of the upcoming junction, but if two turnings are close together, both appear on-screen with the following turning displayed in a slightly smaller graphic just above the first. Plus, when approaching the junction, a small progress meter is displayed that shows how close you're getting. You can also tap the icon to have the voice instructions repeated.
Another brilliant feature is the map browse and route planning tool. Tap the magnifying glass icon in the bottom right-hand corner of the screen and you're taken directly into map browse mode. From here you can zoom in and out quickly, get a quick overview of the whole route, pan about by dragging your finger and add points to your route quickly and easily. It's fantastically simple - and even better than TomTom's more round-about way of doing it.
