U0184 on Chevrolet by model: symptoms, diagnosis and fix
The infotainment system can freeze, display a black screen, or reboot randomly. This affects navigation, audio, backup camera, and vehicle settings. Software bugs and hardware failures are both possible causes.
Common Symptoms
- Screen goes black
- System freezes
- Random reboots
- Backup camera not displaying
- Bluetooth issues
- Touch not responding
How to Fix
Update infotainment software to latest version. Perform system reset. If problems persist, the infotainment module may need replacement. Check for GM service bulletins or recalls.

Trucks with the larger Google Built-in infotainment system (rolled out on the refreshed 2022+ Silverado 1500 interior and continuing through 2024-2025) suffer frequent screen freezing, full lockups, Bluetooth dropouts, navigation errors and streaming-audio (e.g., Spotify) lockups. Owners commonly have to switch the ignition off and wait several minutes for the head unit to recover. Internal GM bulletins attribute many freezes to the system being overloaded when processing too many tasks at once, and to communication errors between the infotainment system and the body control module. This is a newer-generation, Google-OS-specific complaint distinct from earlier MyLink/Infotainment 3 freezing on pre-refresh trucks.
Common Symptoms
- Infotainment screen freezes or goes black
- System lockup requiring ignition cycle
- Bluetooth disconnects
- Navigation errors
- Streaming audio (Spotify) lockups
- Backup camera glitches
How to Fix
Apply the latest GM software/over-the-air updates, which have targeted several freeze/reboot bugs; perform an infotainment system reset (or battery disconnect) to clear a lockup; check for applicable customer-satisfaction programs by VIN. Persistent failures may require head-unit/module reprogramming or replacement under warranty.

The MyLink infotainment system can freeze, become unresponsive, or reboot randomly. This affects the radio, navigation, backup camera display, and phone connectivity. Issues are often software-related but can indicate hardware failure.
Common Symptoms
- Screen freezes and won't respond
- Random reboots while driving
- Bluetooth won't connect or stay connected
- Backup camera display issues
- Volume controls unresponsive
- Black screen
How to Fix
Update to latest software version via dealer or USB. Perform a hard reset by holding power button. Clear paired Bluetooth devices. If problems persist, the radio module may need replacement under warranty or extended coverage.

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. This is one of the most-searched Equinox electrical complaints across model years.
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.

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. Software stability issues have been addressed through multiple OTA updates.
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.

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, Equinox, TrailBlazer.
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.
