Navigon may have fallen short of greatness with its MobileNavigator for iPhone app, but on paper its latest flagship, dedicated sat-nav looks like it should suffer from no such disappointments. If you're inclined to take Navigon's word for it, the 8410 is both "sleek and technologically innovative."
A 5in glass-fronted touch-sensitive display "that responds to the slightest touch" is a good start to backing up Navigon's claims. However, if pushing icons is just too much effort then the presence of Voice Interaction Pro vocal commands will be welcome, with this iteration promising even to understand colloquialisms. If paired with a phone, via Bluetooth, voice dialling of contacts in also possible from the 8410.
The more usual array of features, such as lane assistance and point of interests, are present, too, and in select European cities photo-realistic mapping is available. As if all that wasn't enough, the 8410 can double as a media player and a DVB-T model is available, making the sat-nav usable as a TV in addition to its normal duties.
At £399.99 the Navigon 8410 is hardly at the budget end of the sat-nav spectrum, taking on the similarly priced (and fantastic) TomTom Go 930. You'll be able to get your hands on the 8410 come September should you be interested.
