# Service bulletin L\-TT\-0121\-13

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

Tech Tip: My 2013 Gen 7 navigation systems use a USB SST to update the firmware and map. MY 2014 IS and GX models incorporate a Gen 8 navigation system that uses a USB stick to update the firmware ONLY. Refer to the chart below for a comprehensive list of all current and previously issued USB SSts and their applicability.
