TSB: Some 2018 ? 2020 model year Lexus vehicles equipped with the Enform? 2.0 Navigation
System require a Special Service Tool (SST) USB flash drive to update the map, points of
interest, and system software. The SST is used with applicable vehicles to deliver the update;
however, the process for generating license keys differs from previous generations.
Before attempting to perform a map update, the head unit?s expiration date must be checked.
If the expiration date is still valid, a license key may be generated without the use of an activation
card number. Updating the maps without the use of an activation card number is considered an
Embedded Navigation Update (refer to pg. 10) and performing this process does not extend the
duration of telematic map services. If the head unit?s expiration date is expired or will expire within
the next 90 days, it should be recommended to the customer to purchase an activation number.
Utilizing an activation number will initiate a Dynamic Navigation Update (refer to pg. 4). This
Dynamic Navigation Update will perform the Embedded Navigation Update and provide telematic
map services for a period of two years from the day that the Dynamic Navigation Update
is performed.
Activation card numbers are provided in an activation card number pamphlet available through the
normal parts ordering system.
