## NHTSA's summary

TT: Refer to the chart below for a comprehensive list of the current and previously issued USB SSTs and their applicability. This is only a reference list of tools that might be in dealership inventory and not meant to be a diagnostic or repair procedure. Generation 7 navigation systems use a USB SST to update firmware and map. Generation 8 navigation systems use a USB stick to update the firmware only.
