As to my old Navi (Becker Traffic Assist) the maps could no longer update, I needed a new one. Since the market is in the meantime very 'clear', only two products were shortlisted: Navigon & Becker (Garmin & TomTom are not so my world. When Navigon, a good but already betagtes device was not about to find out how long it will give map updates or when it will be completely swallowed by Garmin. So there was only the Becker navigation device, although I did initially doubt the reviews regarding the customer recessions. The Content Manager. Finally, I 'the leap of faith' ventured - and lo and behold, the device is working properly! - Unpacking Install, Connect, etc. ... Enter target (over a distance of at least 10 km), drive off; Refer Navi from something hakligen passive holder -; - Insert Micro SD Card! (My 4 GB) - Connect to the PC and the specifications of the Content Manager will follow! - Sign; Create backup copy of the Content Manager - - Download Updates That's the whole secret! - It funzt !!! And Katrin has kept her voice! One puzzle still remains: Why is this device has not been settled and a holder which is equipped with the same simple closure of the active holder ?! - Therefore, only 4.5 star!
