-capable mobile
phone is required.
On COMAND
X Activate the Bluetooth ®
function in
COMAND (Y page 45).
On the mobile phone
X Switch on the mobile phone and enter the
PIN when prompted to do so (see the
manufacturer's operating instructions).
X Activate Bluetooth ®

operating instructions).
The battery of the mobile phone should
always be kept sufficiently charged in order
to prevent malfunctions.
Preparing for telephony via the Bluetooth ®
interface:
R Hands-Free Profile
The mobile phone must support Hands-
Free Profile 1.0 or above.
