The Chevrolet Infotainment 3 system freezes, goes to a black screen, or reboots spontaneously. Bluetooth connectivity drops and Apple CarPlay/Android Auto connections are lost. The system may become unresponsive to touch input, requiring a manual reboot. On 2021 models GM issued Service Update N202316020 (June 2021), a radio software update delivered over the air or by the dealer, for a black screen with no audio or chime at key-on in cold temperatures.
Common Symptoms
- Screen freezes or goes black
- System reboots while driving
- Bluetooth disconnects repeatedly
- CarPlay/Android Auto not connecting
- Touchscreen unresponsive
How to Fix
Check for and install any available OTA software updates through the Settings menu. Perform a hard reset by holding the power/volume knob for 10+ seconds. If issues persist, the dealer can reflash the infotainment module to the latest software. Clear paired Bluetooth devices and re-pair. In rare cases, the infotainment module hardware must be replaced.

The center touchscreen (Chevrolet MyLink / Infotainment 3) intermittently goes completely black, freezes, or reboots in a loop while the rest of the car operates normally. Owners lose the backup camera, climate display, radio, Apple CarPlay/Android Auto, and OnStar screen. The failure is usually a software/HMI-module fault but is also commonly traced to loose or corroded connectors and cables at the radio receiver located behind/below the glove box, or to a failing HMI (Human-Machine Interface) display module. A temporary fix is a system reboot (hold the power/volume knob ~10-15 s, or hold Home + fast-forward for 10 s), but it returns until the underlying module or wiring is addressed.
Common Symptoms
- Touchscreen goes fully black while driving but the car keeps running
- Screen reboots in a loop or freezes on the Chevrolet logo
- Loss of backup camera image, radio, and climate display
- Apple CarPlay / Android Auto drops out repeatedly
- Screen comes back after a manual reset, then fails again
How to Fix
First attempt the documented soft reset (press and hold the power/volume knob 10-15 seconds, or Home + Seek-Forward for 10 seconds) and let the system reboot. If blackouts persist, inspect and reseat the connectors/cables at the radio receiver behind/below the glove box and check for corrosion or a poor ground. Apply any available GM infotainment software update at the dealer. If the HMI display module itself is failing, replace it with a GM-programmed HMI module (plug-and-play replacements are available and are reflashed to the VIN). Confirm CarPlay/camera/climate all return after repair.

Frequently asked questions
What does U0184 mean on a Chevrolet?
U0184 stands for "Lost Communication With Radio." This network code means a module stopped receiving expected communication messages from the radio/audio module over the vehicle's data bus. When the radio module goes offline or its bus connection fails, this code is logged. On some vehicles the audio module also acts as a network gateway, so its loss can trigger several related communication codes. Symptoms are typically a dead or unresponsive radio/infotainment system; it does not affect drivability. On Chevrolet it is documented across 4 models: Silverado 1500, Colorado, TrailBlazer, Equinox.
What are the most common causes of U0184?
The most common causes of U0184 are: Loss of power or ground to the radio/audio module, Blown radio fuse, Wiring or connector fault on the communication bus, Faulty radio/audio control module, Corroded or loose module connector, Network/bus wiring short affecting multiple modules. The specific cause varies by vehicle.
