Positives:
-3D Road layout (even if they sometimes get confused with urban tunnels)
-Höhenangabe The display
-Straßennamen Be visibly displayed
Neutral:
Not always timeliness of street signs after update
Negatives:
- The "Back" button is too cumbersome, when actuated to move always the whole Navi
- The suction mount falls off sometimes, no matter how clean the holder or the disc or what climatic conditions prevail
- The software!!!
-> The software itself depends often on (Windows 7 and 8)
-> You have to constantly re-register, partly even register new
-> The biggest joke is the lifelong updates (improvements of the maps I can not judge). Already for the installation of the first displays the software updates that not enough space is available. So you have to to buy an external memory card in any case. Should hang an update times, one can only hope that you make a backup, otherwise you're unlucky, because a similar rescue CD there is not any.
Conclusion: Compared to other manufacturers, Navi offers a good handling with a large display and a nice traffic routing. In the price range but you could also expect more maps and additives such as speed cameras. These are download only for a lot of money directly to Becker.
Unfortunately, the one lousy software and the insufficient internal memory spoils the fun.
