Aside from searching for Points of Interest by name and navigating to them directly, the 7210 also provides quick access to nearby petrol stations, parking and food by default. But you can change each of these three slots to any of the 25 available POI categories. The quick access only works when you actually have a GPS signal, though, as otherwise the icons are greyed out and can't be selected.
The 7210 incorporates a single USB socket which is used for charging, PC connection, and attaching the RDS-TMC aerial. We found the device could be powered by other mains adapters using a USB connection, such as a Motorola phone charger, which could come in handy. Unfortunately, one trend Navigon hasn't yet followed is the integration of the car power connectivity with the screen mount, so you still need to plug this in separately before securing the 7210 on its cradle. But at least the cradle is relatively easy to use. The 7210 has a port for an external GPS aerial, as well, which not all sat-navs offer these days and will be useful if your windscreen degrades the signal too much.
The Navigon 7210 looks like a formidable sat-nav on paper. It certainly follows all the latest navigational feature trends. However, its interface lets it down, and there are precious few extra utilities. If you're after a premium sat-nav with full European maps, TomTom's GO 730 T (the 530 T but with full European maps) offers similar features for less, whilst Garmin's nuvi 860 provides much better voice capabilities for around the same price.
