Condition	Some customers may comment on software issues. A continuous improvement software update is being released with updates made on the following areas: Bluetooth, Projection (Android Auto/Apple CarPlay), Sirius XM, Display, Instrument Cluster/Driver Information Center (DIC)/Heads Up Display (HUD), and general system improvements. Most notable improvements include: Bluetooth:  Phone contacts may not fully download - This condition may vary with each drive cycle, or each time Bluetooth reconnects. Contacts may be missing, voice recognition (VR) may respond that it cannot find the contact or may indicate that no phone is connected even though the display shows a connection is present. When using Android Auto, the Bluetooth may not reconnect automatically. Sirius XM, Digital (DAB) Radio:  Sirius XM displays XM Loading, or Acquiring Signal. Certain vehicles built with a radio that supports Sirius XM (SXM) new 360L experience which includes both satellite (SAT) and internet (IP) channels may briefly play SXM audio for up to 3 seconds then lose SXM audio. This condition may happen at startup or when switching from another audio source to SXM. Sirius XM audio can be restored by switching to any other SXM channel and will remain functional for the remainder of the drive cycle. Display:  Radio and display inoperative after a remote start event. An excessive parasitic load may cause a dead battery after this condition occurs (Camera and chimes still function during this condition.)

Correction	A new radio software update, version U150, is being released for vehicles equipped with Infotainment system RPO IOS, IOT or IOU, in addition to providing general robustness and stability enhancements. This update includes all enhancements from previous software version releases. This update can occur remotely through in-vehicle prompts from the radio display. However, some customers may decline the vehicle update, or the update may be unsuccessful. Along with the vehicles mentioned above, vehicles in unconnected markets, and fleet customers may need the dealer to reprogram the radio with the new software package.

SERVICE PROCEDURE

The update procedure in this bulletin includes the following four sections:

• Determining Where to Start - Checking for Update Status
• Update Procedure Using Remote Vehicle Update
• Update Procedure Using TIS2WEB (USB Download)
• Troubleshooting

Determining Where to Start - Checking for Update Status

The process used for this update is dependent on the status of the software on the module and if the module already has a remote install package downloaded. To verify if an update package is already on the vehicle, open "Settings" and then scroll to "Updates" on the radio screen.

• If an update is shown under the "Updates" screen, proceed to the Update Procedure Using Remote Vehicle Update  section of this document.

• If no update is shown (see "No Updates Available" image in next section), go to the "About" screen and verify the build number (i.e., U145, U146, etc.). If the build number is less than U150.3, proceed with the software update following the Update Procedure Using TIS2WEB (USB Download)  section of this document.

• If the remote vehicle update CANNOT be completed, the radio must be updated through SPS via USB. Refer to Update Procedure Using TIS2WEB (USB Download)  in this bulletin.

Update Procedure Using Remote Vehicle Update

1. Verify if there is a remote package on the system and check to see which of the below pop ups show.
   • If the remote vehicle update has not been downloaded, select "Start Download," wait for the download to complete and then follow the prompts to complete installation.

   • If no "Start Download" or "Install Now" pop up is displayed, navigate to "Settings" -> "Updates." If there is a remote package on the system, it will display "Install Now" Or "Start Download." If the screen below is shown, then there is no remote update package on the system. Navigate to Settings -> About to verify the software version. If the build number is not U150 or greater, update via USB.

     During installation, the vehicle will be disabled and cannot be driven. Features like door locks, windows and chimes may not work. If you leave the vehicle, DO NOT lock occupants inside.

     NOTE:

     Download may pause due to cellular connection speed. If the download pauses, click resume to continue. If the download takes longer than 30 minutes, see the Troubleshooting  section below.

2. Once the remote vehicle update has completed, verify there are no additional updates. Select "Settings", scroll down and select "Updates." If no updates are available, verify software build is at U150 or greater in "Settings" -> About screen. If confirmed, no further action is required.
