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 IR22.64 and IR22.65 to IR22.66. The national launch for the FOTA
is expected to begin on January 09, 2023.
DISCUSSION:
Vehicles can now receive software updates “over-the-air”. Updates to software will occur in a phased roll-out.
The software is updated through the built-in cellular modem in the radio. Customers will see a notification
on their radio screen when new software is available for their radio (Fig. 1) . The customer 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 and any symptom/condition that this enhancement corrects. This
document does not contain a LOP for reimbursement.
