I bought this handset to complement an existing set, including bluetooth. Advertising shows that we can synchronize Gigaset products with the computer's address book, which allows you to update its repertoire more easily than on the phone itself. Unfortunately, this service does not work, despite several appeals from Siemens. I do not understand that Siemens can not determine why sync does not work, not even via USB cable. Always boats answers. Apart from that the device is excellent.
