Service bulletin B650916

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Radio / Navigation / Head Unit Identification. INFORMATION Overview The attachments to this bulletin provides a chronological overview of radio/navigation/head units used in recent BMW vehicles along with their option codes, model applications, service modes and other pertinent information. Security Features Early vehicles, up to E36, use radios that utilize a Security Code to ensure they cannot be used if stolen from a vehicle. For information on identification of these radios and how to obtain the Security Code please reference SI B65 05 99. Vehicles starting with E38 use New Generation (NG) radios that utilize K/I bus security to ensure they cannot be used if stolen from a vehicle. These radios will only function when they see bus communication on the body bus communication line. Starting with the Car Communication Computer (CCC) Head Unit we began using FSC Enable Codes to turn on different functionalities in a head unit. These head units are VIN burnt and if swapped into a different vehicle will cancel all loaded enable codes. You will have to contact technical service to create new enable codes for the head unit if it was swapped for testing. Navigation Data Please reference the SIB specified, in the following table, for information on the different available Navigation Software versions.
