Since there is no more Uploades gave for my Becker Z103 - unless 60 EURO -, I opted for the new READY 50 EU20 with Lifetime Map Updates. A decision I have not regretted, even if there was an unpleasant surprise when you install the software: I had "Acronis 2012" on my PC with Windows 7, a program that was able to prevent the installation! After a - somewhat complex - uninstall this program Acronis but installing the software packages, performing the backups and the registration went effortlessly. In practice, the Navi is proving to be very good device: faster GPS reception, fast route calculation, route guidance good - at least with the male speaker, date maps, pleasant display view, useful "back button" and features. The main problem is the included bracket, because you do not get into the unit without skill. Because the announcements sometimes come a little early and the touch-screen - depending on the thickness of a finger and nail length - not as good addresses of other devices, but you can get used to easily. Conclusion: If you want a good, suitable field device does not have a bad purchase if he does not find the issues or it skillfully white.
