B12 Q
How long does it take to establish a connection?
A
After you have paired your mobile phone with the interface once (see
operating instructions), subsequent connections will take place
automatically (as long as no more than 4 other mobile phones have
been paired).

connection was ended correctly by the appropriate BT functions.
If the connection was ended because the mobile phone was moved
outside the transmission field or the car ignition was switched off or on,
you will additionally have to wait for the mobile phone timeout to
elapse (approx. another 25 - 35 seconds).

range and altered propagation conditions compared to the hands-free
connection.
