The TomTom Via 1535 TM offers many features and services to increase driver safety and routing efficiency.
Though the affordable price tag and text-to-speech functionality are nice, the Navigon 2100's sluggish performance and roundabout route recalculations are a turnoff; you can get a better entry-level portable navigation device in the Mio C230.

Thin, light and clad in metal and glass, the Nuvi 3760 is the first portable nav device that's tugged on our heart as well as our mind. If you can, make the financial stretch to the 3790T as that model offers a brilliant voice recognition system.
With a keen price, and minus the frustrating voice-recognition system found in the rest of the range, the Via 220 proves that less is more; but still not enough to earn it top marks.
Same, same but slightly better than before. Quicker responses and lane guidance justify slight premium over fourth-gen One.
Premium GPS devices have to try harder than ever to stay relevant in the smartphone age. By marrying a crash camera into its hero GPS, Navman's made that effort, producing a device that serious drivers will get exceptional value from.
