LSB: Lexus models equipped with the HDD Navigation (EMV-N) System require a Special Service Tool
(SST) USB drive to update the map, points of interest, Gracenote®, and system software. The SST
is used with all vehicles to deliver the update, however a unique Activation Number is required for
each vehicle. Activation Numbers are provided in an Activation Card Number (ACN) pamphlet
available through the normal parts ordering system. Use the process described in this bulletin to
perform the update.
