Fixing no Audio with Bluetooth Install on e53 and e39
 

Contributed by: UCrewX5


MODEL

E39, 5 Series from 09/00 (without DSP, or Nav system)
E53, X5 vehicles from 10/00 (without DSP, or Nav system)

SITUATION
After installation of the BMW Bluetooth Phone System, the CPT 7000
Phone System, or the CPT 8000 Phone System, there is no audio heard
during the "hands free" operation of the phone.

CAUSE
The connector X13598 (for the telephone audio signal) has been disconnected from the socket (X18126) at the back of the New Generation radio. Connector X13598 has been disconnected during production in order to eliminate audible disturbances in the sound system (I-bus signals crossing to the telephone cable).

CORRECTION

Reconnect the X13598 connector at the back of the radio module.
