1. Speed alarm disturbs - off warning
2. Proximity Alerts have no adjustable tolerance - can be in transferring the POI Loader define itself
3. intermediate objectives must be approached - off recalculation, continue until you route reached again, Navi on standby, turn it back on, do not be at Danger waypoint will be ignored or even off for route planning in Base Camp at the intermediate targets the proximity alert (if the stopover is not essential to one is). As a result, you can leave the route at any time and will continue to navigate the same again at the recent achievement.
4. made with Basecamp routes in the transmission recalculated with the result of another route - navigation device logs in to the transfer only if the route has too many targets, then the route is divided, but not recalculated.
5. If you switch the Navi completely made, will no longer be navigated after - if you have not switched the Route menu to stop, you will be prompted on reboot to continue the route.
In direct comparison with the 660, the Navitationsgerät was absolutely convincing (if a MP3 player and the phone function are not mandatory).
Ua the route construction is faster, the display is brighter and easier to use, at the address input is no longer available letters on the keypad are hidden, the display of the lane assistant is better resolved, the unit itself is compact and less sensitive to external influences.
In my view, a clear recommendation.
