Service bulletins for the 2016 BMW 428i

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.

6513122018-11-13. Service bulletin. EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM); EQUIPMENT. This Service Information bulletin supersedes SI B65 13 12 dated September 2012. designates changes to this revision SUBJECT Headunit High: Navigation System Road Map Usage. INFORMATION The Headunit High (HU-H), also called NBT, began replacing the Car Information Computer (CIC) on certain MY2013 vehicles with option 609. This change will affect the navigation system road map data support process and the warranty spare parts processes for the HU-H. For the US market, all vehicles will come pre-loaded from the factory with the latest navigation system road map database version that was available at the time of vehicle production. Therefore, there will be no physical copy of the navigation system road map data media DVD set or USB stick placed in these vehicles at the Vehicle Distribution Center (VDC). NOTE: Additionally, all replacement HU-H parts come with a pre-loaded version of the current available navigation system road map database installed. A set of DVD copies of the navigation system road map database, HU-H NAVI Road Map North America NEXT, is shipped to all BMW centers through the automatic tool shipment program with each release of a navigation system road map database. IMPORTANT: Additional copies or earlier NAV road map database versions cannot be ordered individually! Therefore, please take special care to archive the HU-H NAV road map DVD sets! The NAV road map data on the DVD set can also be installed into the Network Attached Storage (NAS). From there it then can be installed onto the HU-H in the vehicle, using the Integrated Service Technical Application for Programming (ISTA/P). For installation of the navigation system road map data media DVD set onto the Network Attached Storage (NAS), please contact your ISPI NEXT Administrator. In addition to this procedure, it is also possible to download the NAV road map data on the DVD set directly to the hard disc drive (HDD) integrated in the HU-H by inserting the DVDs one by one into the HU-H internal DVD
