# Service bulletin 15\-248\-19

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

When a NEW \(NOT exchange\) Harman Gen 3.0, 3.1 or 3.1 Alpha head unit \(H/U\) ordered through a Subaru RDC / PDC \(warehouse\) is installed, the serial number of that unit is not to linked a specific VIN. As a result, the customer will not be able to receive any Firmware Over\-The\-Air \(FOTA\) updates due to a VIN / H/U serial number mismatch. In order to ensure compatibility with future FOTA updates, the Retailer must capture the complete 28\-digit serial number of the NEW H/U and share that information with SOA. The preferred method for sharing the information is by submitting a COMPLETED QMR which should include a clear photo of the serial number label for use as a cross\-check to ensure accuracy. This same procedure is required if a Harman Head Unit is swapped from another vehicle then left in the “new” vehicle. In this case, same as above, submit a COMPLETED QMR which also includes a clear photo of the serial number label for use as a cross\-check to ensure accuracy along with the “new” vehicle’s VIN.
