The device itself is fine, unfortunately it always forgets the autozoom if you eimal zoomed manually. Grottig contrast, the service of Becker. One is compelled to defects hotline for 89ct. / Min. to call, because the e-mail through the contact, although the feedback that they would make themselves known within 4 days coming, but then takes no PARTNUMBERS response. Since this is only a defective charging cable are the cost of postage and telephone hotline higher than the price of a different charger cable. This was my 4th and last-Becker Navi.
