Official summary

The MBUX system will receive an OTA update that includes general product improvements and robustness enhancements for the “Live Traffic Information” and “Point of Interest” (POI) features.

Vehicles covered

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
