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.) • Radio freezes when there are 10 paired devices in Bluetooth menu. Pressing Home recovers this condition. • Push to Talk (PTT) screen displays at startup and self recovers • Display freezes (Encore GX only) • Part of text is truncated in Running Applications page (Korea only) • Instrument Cluster, DIC, HUD: • Intermittently when placing a Bluetooth call, the HUD may show the call still active after the call has ended (Encore GX only) • Korean text lines are too close to read the info on HUD (Encore GX only) • Song list in DIC may be blank when searching • Service tech may experience Instrument Cluster USB update fails. • System: • The FM Browse feature only lists the most recent FM station (Non-HD Radios [U2L or U2M] only) • Radio stuck in Valet mode. Unable to unlock with correct password/PIN • Delayed Door Lock menu displays incorrectly when Anti-Lockout setting is enabled, allowing two options to be selected • Performance Data Recorder (PDR) displays status bar and black screen only when in Park after rejecting an incoming call (Camaro only) • Automatic Time Zone setting is greyed out • Unable to list or play AVI/MP3 files • Over the Air (OTA) update popup does not expire until Accepted or Declined • OnStar Location Services switch is off and displays Location unblocked popup in Turn by Turn (TBT) when selecting Yes. • RDS Traffic Alerts may not play or display correctly while using Android Auto or Apple CarPlay. Cause The cause of the condition may be software anomalies. 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. Bulletin No.: 20-NA-199 November, 2020 Service Procedure Important: Some technicians are reporting that the radio remains on v148 after the radio displays the software update completed successfully. It is important to ensure that the technician is inspecting the Build Number and not other rows of information on the same screen. This requires the user to locate the Build Number, and then select the Information icon (circled Page 3 lower-case i) to see the full software version file name. In these radios, the build number could be W124E after installing U150. This W124E is NOT the software version and is not unique to the U150 software release. Important: After pressing the information icon, review the full software version file name. In the middle of this long file name you see the U150.3. 5662668 Page 4 November, 2020 Bulletin No.: 20-NA-199 5662665 Important: If the remote vehicle update has been downloaded or installed, DO NOT install the update via USB.
