Service bulletin A911584 2040579-

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

During PDI, the Navigation function is found to not be available. The error message "Navigation data is invalid" appears in the MMI. During a certain production period, the supplier of the MMI main unit, Harman, incorrectly configured the software for the MMI. As a result, Navigation cannot be activated.
