# Service bulletin 15\-245\-19R

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

This bulletin provides a new reprogramming procedure \(FOTA\) to optimize the Harman Gen 3 Audio and Navigation head units \(H/U\) utilized in the models as listed above. Firmware\-over\-the\-air \(FOTA\) is a process by which remote devices can receive updates to their operating software. This process has become second nature with smartphones, tablets and many other connected devices. FOTA for automotive infotainments systems has been designed with a similar type of customer convenience in mind. FOTA updates are designed to provide regular enhancements along with some software patches to our infotainment systems improving the user experience for our customers. The convenience factor comes not only with the supply of regular updates and the enhancements they provide but also through customer control of when these updates are applied by allowing them the freedom to choose when these updates are downloaded and installed. All that is required is a secure WiFi connection such as through a home network or the use of a secure WiFi hotspot to create a connection to the update server and any customer can obtain and install an available FOTA update to their infotainment head unit. In this bulletin we are focusing on FOTA for Harman Gen 3.0 MIDlevel audio systems and Gen 3.0 HIGH audio\-navigation systems. BASE models are not FOTA capable. This bulletin will describe in greater detail the process for how FOTA is accomplished as well as provide insights and some procedures for how to resolve conditions that may arise as a result of audio or audio/ navigation head unit swaps or replacements performed outside of the Harman/ United Radio exchange unit program.
