These downloads are accessible in Canada only for select Canadian Lexus vehicles. Do not attempt to apply firmwares to multimedia units for which they are not intended.

Although firmwares are updated to correct concerns and enhance functionality, there is the possibility that existing functionality may no longer be available, or functionality may change significantly.
