REPAIR SUMMARY:
This bulletin provides information regarding the latest Firmware Over The Air (FOTA) update and provides
the service technician an overview of the steps a customer will need to take to complete the update. The
radio software will be updated from S26.18 to T25.50.

DISCUSSION:
Vehicles sold in the U.S. and Canada can now receive software updates “over-the-air”. Updates to software
will occur in a phased roll-out. The software is updated through a built-in cellular modem in the vehicle.
Customers will see a notification on their radio screen when new software is available for their radio (Fig. 1) .
The owner will have the option to update the radio or schedule the update for later. There is not an option
to decline the update indefinitely, the update must be performed.
NOTE: This is an Information Only Technical Service Bulletin to inform the dealer how the FOTA
update is performed. This document does not contain a LOP for reimbursement.
