Service bulletin ITB21-011
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
DIAGNOSING SOFTWARE VS. HARDWARE AV ISSUES SERVICE INFORMATION When diagnosing audio visual infotainment issues, confirming whether the issue is software or hardware based can be difficult to determine. To help the diagnostic process, a comparison of hardware vs. software issues and recommended resolutions has been provided in TABLE 1 on page 2. In most cases replacing an AV unit that has a software concern with the same level part will not correct the issue. First, check ASIST for the latest related bulletins, and use the correct software package or Over The Air (OTA) updates, if available. • As of the publication date of this bulletin, global shortages of raw materials have resulted in a very limited supply of AV units. Do not replace an AV unit unless it is absolutely necessary. • Refer to the 2021 February-March Tech Talk article “Hardware vs. Software” for additional information.
