First start: the menu navigation is simple and effective, the number of options is quite broad and little updating. To create a course, history, add POIs is simple and well guided.
On the road, no complaints: the voices are clear, fast route calculation, the explanations provided (especially during interchanges with lots of channels).
However some negative points: first the autonomy is small which considerably limits are pedestrian use. Furthermore, the maps update is atrocious: it must connect to the TomTom website, disable any antivirus and firewall at the risk of even blocked procedure. Once done, however, remains the SHIFT very long (almost 4 hours with an ethernet connection to about 12 Mega).
Despite all the GPS is a very good choice, excellent quality / price!
