2024-2025 Jeep Wrangler/Gladiator Radio Software Update TSB

Owners of 2024-2025 Jeep Wrangler and Gladiator vehicles may encounter various issues with their Uconnect 5 Nav W 12.3" Display radio system. Technical Service Bulletin (TSB) 08-131-25 outlines a Firmware Over-The-Air (FOTA) software update designed to resolve these concerns. This Jeep Wrangler radio software update applies to vehicles built on or before April 21, 2025 (MDH 0421XX) that are equipped with a Global Telematics Box Module (Sales Code RDG) and either the Uconnect 5 Nav W 12.3" Display (USA) (Sales Code UBX) or the Uconnect 5 Nav W 12.3" Display (CAN) (Sales Code UEX).

Symptoms

Customers may experience one or more of the following symptoms related to their Uconnect radio system:

• "Pop-up messages text cut-off "Transfer to Passenger"".
• Missing active call details in the phone widget after a call swap is performed.
• Missing Pop-up messages for Blind Spot related to Lane Management being turned on or off.
• A "Virtual wall option" appearing in the menu that should not be present.
• The need to select "Sound type" in EV pages twice.
• The "Apple Car Play icon on main screen disapears when ACP is active".

Important Warnings

This TSB includes critical information for owners and technicians:

• "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." This means that while the bulletin provides guidance, it does not authorize labor operations for dealer reimbursement, which could imply costs for the owner if the vehicle is out of warranty or if the update is not covered by a separate campaign.
• Software updates are delivered "over-the-air" in a phased rollout. Customers will receive a notification on their radio screen when new software is available. While owners have the option to update immediately or schedule it for later, there is no option to decline the update indefinitely; "the update must be performed."

Diagnosis and Trigger Conditions

These issues are caused by earlier software versions, specifically U33.43 and U35.18, installed on the Uconnect 5 Nav W 12.3" Display radio system. The problems are resolved by updating the radio software to version U37.23. The update is delivered via the vehicle's built-in cellular modem.

Repair Procedure Summary

The Jeep Wrangler radio software update is performed via a Firmware Over-The-Air (FOTA) process. When a new software version is available, customers will receive a notification on their radio screen. The update process involves the following steps:

1. The vehicle must be in 'Park' and the ignition in the off position.
2. If the customer selects "Update Now" from the notification screen (similar to Fig. 1, which shows a "Software Update Screen" indicating new software and features are ready), they can shut off the vehicle and leave. The update will be completed automatically.
3. This update process may take several minutes to complete.
4. Upon successful completion, the radio will display a confirmation message (similar to Fig. 2, which shows a "Software Update Confirmation Screen" stating, "Your UConnect system has been updated with the latest Software.").

Owner Action

If you own a 2024-2025 Jeep Wrangler or Gladiator and experience any of the described Uconnect radio issues, be aware that a software update is available. Look for a notification on your vehicle's Uconnect screen regarding a new software update. The national launch for this FOTA update is expected to begin on May 05, 2025. Ensure your vehicle is in 'Park' and the ignition is off when initiating the update.
