If your Chevrolet Trax audio system suddenly goes silent, the problem is often more specific than a bad radio.
This guide explains how to fix 2015 Chevy Trax radio not working by tracing the fault from fuse and power issues to software, wiring, and module problems.
Common symptoms of a 2015 Chevy Trax radio failure
The infotainment system in the 2015 Chevrolet Trax can fail in a few different ways, and the symptom usually points to the likely cause.
Some issues are electrical, while others are related to the MyLink head unit, radio display, or vehicle software.
- The screen stays black or does not boot up.
- The radio has power but no sound comes from the speakers.
- Buttons work intermittently or freeze.
- The display shows the Chevrolet logo and restarts repeatedly.
- Bluetooth, USB, or AM/FM functions stop responding.
- Only the clock or backlighting works, but no audio functions are available.
Check the basics first
Before replacing parts, confirm that the issue is not caused by a simple setting or temporary glitch.
Turn the ignition fully off, open the driver door, wait a few minutes, and restart the vehicle.
This gives the infotainment system time to shut down completely and reset.
Also check these items:
- Volume level and mute setting
- Audio source selection, such as Bluetooth, AUX, or radio
- Fader and balance settings
- Phone pairing status if audio is routed through Bluetooth
- Steering wheel audio controls for response
Inspect the radio and infotainment fuses
A blown fuse is one of the most common causes of a dead radio in the Trax.
The 2015 Trax uses multiple fuse circuits for infotainment, accessory power, and related modules, so a single fuse fault can disable the radio or the display.
Use the owner’s manual or the fuse box cover diagram to locate the correct fuse panels.
Check the infotainment, radio, accessory, and body control module fuses with a fuse puller or test light.
Replace only with the same amp rating.
If the replacement fuse blows again, there is likely a short circuit or another downstream electrical fault that needs diagnosis before further replacement.
Perform a soft reset on the radio
Many GM infotainment systems respond to a reset after a temporary software lockup.
If the screen is frozen or the radio is unresponsive, try a soft reset before assuming hardware failure.
Common reset methods include:
- Turning the vehicle off, opening the door, and waiting several minutes
- Disconnecting the negative battery terminal for a short period, then reconnecting it
- Holding the power/volume button, if the unit responds to button input
After a reset, check whether the system reboots normally.
If the problem returns frequently, the issue may be deeper than a temporary glitch.
Test for power, ground, and speaker output
If the radio appears to turn on but no audio plays, the head unit may still have a wiring or output problem.
A multimeter or test light can help verify whether the radio is receiving proper voltage and ground.
Key checks include:
- Battery voltage at the radio connector
- Ignition or accessory power signal
- Chassis ground continuity
- Speaker output continuity from the radio to the speakers
A loss of power or ground usually points to a fuse, connector, harness, or ignition circuit issue.
If the unit has power but no sound, the problem may be in the amplifier, speaker wiring, or the radio’s internal audio output stage.
Look for wiring or connector damage
The 2015 Chevy Trax is a compact crossover, and vibrations, moisture, or prior repairs can create connector problems behind the dash or in related harnesses.
Loose plugs, bent pins, and corroded terminals are all common causes of intermittent audio failure.
Inspect the wiring around the head unit, fuse boxes, and any amplifier locations.
Pay attention to areas that may have been disturbed during stereo upgrades, dashboard work, or battery replacement.
If the vehicle has aftermarket accessories, such as remote starters or non-factory radios, they can also interrupt the factory audio circuits.
Check for battery and charging system issues
Low system voltage can cause the Chevrolet MyLink radio to behave erratically.
If the battery is weak or the alternator is charging poorly, the infotainment system may reboot, freeze, or shut off entirely.
Measure battery voltage with the engine off and running.
A healthy battery should generally read around 12.6 volts at rest, and the charging system should usually raise voltage to the mid-13 to low-14 volt range when the engine is running.
If voltage is unstable, fix the battery or charging issue first, then retest the radio.
Update or reinitialize the infotainment software
Software faults can affect the MyLink system, especially if the radio is stuck on startup, has touchscreen problems, or loses certain functions after a battery event.
In some cases, the system may need a dealer-level software update or module reprogramming.
Signs that software is involved include:
- The radio works after a reset but fails again later
- Menus lag, freeze, or misread inputs
- Bluetooth pairs inconsistently
- The display shows unusual boot behavior
For some vehicles, a GM dealer or qualified automotive electronics shop can check for service bulletins and software updates related to the 2015 Trax infotainment system.
Check speaker and amplifier problems
If the radio turns on but there is no sound, the head unit may not be the only component at fault.
A failed speaker, damaged speaker wire, or amplifier problem can make the system seem dead even when the radio itself is functioning.
Try these checks:
- Test each speaker for sound individually
- Listen for static, popping, or a single-channel failure
- Verify whether sound returns when switching sources
- Inspect any factory amplifier connections if equipped
A single shorted speaker can sometimes trigger protective shutdown behavior in the audio system, so isolating the affected circuit can save time and expense.
Know when the head unit has failed
If the fuse, wiring, reset, voltage, and software checks do not solve the problem, the radio head unit itself may have failed.
Internal circuit board damage, screen failure, or corrupted memory can leave the system unusable.
Typical signs of head unit failure include:
- No response even with verified power and ground
- Repeated reboot loops
- Dim or dead display with no button response
- Persistent audio failure after all external causes are ruled out
At that point, replacement or professional repair is usually more practical than repeated troubleshooting.
Professional diagnosis can save time
Because the 2015 Chevy Trax radio is tied into the vehicle’s electrical and data systems, a scan tool can help identify faults in the body control module, infotainment module, or related communication networks.
That is especially useful when the problem is intermittent or appears after a battery disconnect, jump start, or accessory installation.
A qualified technician can quickly verify whether the fault is in the radio, the speakers, the wiring, or the vehicle network, which helps avoid unnecessary part replacement.
Prevent future radio problems
Once the radio is working again, a few habits can help prevent repeat failures.
Keep the battery in good condition, avoid low-quality accessory wiring, and use proper fuse ratings after any repair.
If the infotainment system starts freezing intermittently, address it early before the issue becomes a complete loss of function.
- Maintain battery health and charging performance
- Avoid forcing connectors or damaging dash trim during repairs
- Use factory-compatible accessories and harness adapters
- Check for software updates when symptoms begin
