Principles of Operation: Contacts
The Contacts menu is a database for managing names, addresses and telephone numbers.
Data that is displayed both in the phonebook as well as in the navigation system is stored in this central address database.
The phonebook data is transferred through the currently paired mobile phone using a PBAP protocol (Phonebook Access Profile).
The imported entries from a paired bluetooth phone are identified by the Bluetooth icon next to the telephone entry.
An option for exporting all contact data back into the mobile phone is not provided.
Entries made under "New contact" are retained even after uncoupling the telephone and can be edited at any time. Initially, these contacts are shown without a symbol. A navigation symbol is added at the end of the entry when an address has been added.
