Using the phone book
Introduction
If the mobile phone supports downloading
contacts via PBAP (Phone Book Access Pro-
file), the mobile phone book will automatically
download to the Audio 20 system when con-
nected. You can also import contacts to the
phone book from a USB device or use Blue-
tooth ® to receive vCards.
i The phone book can store between 1,000
and 2,000 entries, depending on the size of
the entries. Imported vCards are given pri-
ority when storing and overwrite existing
PBAP contacts if the memory is full.
i Imported contacts are stored perma-
nently in the phone book. For this reason,
you should delete the call lists before sell-
ing the vehicle.

phone; see (
