Peugeot 308 Radio Not Working: Complete Fix Guide

If your Peugeot 308 radio is not working, silence can feel louder than engine noise. One minute you're cruising with your favorite playlist, the next—nothing. Blank screen. No sound. Frozen display. It’s like the car suddenly decided to take a vow of silence.

We’ve all been there. And the good news? Most Peugeot 308 radio issues are fixable—sometimes in minutes, sometimes with a bit more patience. In this comprehensive guide, we’ll break everything down clearly and casually, just like we’re troubleshooting it together in the driveway.

Understanding the Peugeot 308 Infotainment System

Before we jump into fixes, let’s understand what we’re dealing with.

The Peugeot 308 has used different infotainment systems across generations:

• RD4 (older models)
• SMEG / SMEG+ system
• NAC system (newer touchscreen units)

Each system behaves slightly differently. Knowing your version matters because a frozen SMEG screen isn’t fixed the same way as an older RD4 radio.

Common Symptoms of a Peugeot 308 Radio Not Working

When drivers search “Peugeot 308 radio not working,” they usually mean one of these:

• No sound at all
• Radio turns on but no audio
• Touchscreen frozen
• Screen completely black
• Bluetooth not connecting
• Radio keeps rebooting
• Only FM works, no DAB
• Radio stuck on Peugeot logo

Sound familiar?

Let’s break down each scenario.

No Sound but Radio Turns On

This is one of the most common complaints.

You see the screen. You can change stations. But it’s silent.

Possible Causes:

• Muted system
• Faulty amplifier
• Speaker wiring issue
• Software glitch
• Blown fuse

Quick Fix Checklist:

• Check volume (yes, really)
• Make sure it’s not muted
• Test Bluetooth and AUX
• Restart the system
• Inspect fuse

Sometimes it’s something simple. Other times, it’s deeper.

Peugeot 308 Radio Screen Completely Black

A black screen feels dramatic. But don’t panic yet.

Why This Happens:

• System crash
• Blown fuse
• Loose wiring
• Dead head unit
• Battery voltage issue

First Step: Perform a Hard Reset

For most Peugeot 308 models:

• Hold the power button for 10–15 seconds.
• Wait for system reboot.

If that doesn’t work:

• Disconnect the battery for 15 minutes.
• Reconnect and test again.

This alone fixes a surprising number of cases.

Touchscreen Frozen or Unresponsive

When the screen won’t respond, it’s usually software-related.

Common Causes:

• Outdated firmware
• Glitch during Bluetooth pairing
• USB malfunction
• System overload

What We Can Do:

• Restart the system
• Remove USB devices
• Delete paired phones
• Update firmware

Software updates often resolve persistent freezing.

Peugeot 308 Radio Keeps Restarting

If your radio keeps rebooting like it’s stuck in a loop, this usually points to:

• Corrupt firmware
• Internal hardware failure
• Voltage irregularity

This often affects SMEG systems more than older RD4 units.

A firmware reinstall might fix it. If not, replacement could be required.

Bluetooth Not Working in Peugeot 308

Bluetooth issues are extremely common.

Symptoms:

• Won’t connect
• Keeps disconnecting
• No audio through Bluetooth
• Microphone not working

Quick Solutions:

• Delete phone from car system
• Delete car from phone
• Restart both
• Re-pair from scratch

If that fails, update infotainment firmware.

Blown Fuse Causing Radio Failure

Let’s talk about something often overlooked.

A simple fuse can disable the entire radio.

How to Check:

1. Locate fuse box (dashboard or engine bay)
2. Identify radio fuse
3. Remove and inspect
4. Replace if blown

Cheap fix. Huge relief.

Battery Issues Affecting the Radio

Low voltage can make infotainment systems behave strangely.

If your battery is weak:

• Screen may flicker
• Radio may reset
• Bluetooth may drop
• Display may fail to turn on

Always check battery health before replacing expensive components.

SMEG System Problems in Peugeot 308

SMEG systems are powerful but known for glitches.

Common SMEG Issues:

• Random rebooting
• Touchscreen freezing
• Bluetooth dropping
• Audio cutting out

Sometimes a firmware update solves it. Sometimes internal memory failure requires replacement.

RD4 Radio Problems in Older Peugeot 308 Models

RD4 units are simpler but not immune to faults.

Typical Issues:

• No sound from speakers
• Radio locked (requires coding)
• Faulty volume knob
• Display issues

Replacing an RD4 is usually cheaper than newer systems.

How to Reset Peugeot 308 Radio Properly

Let’s walk through it step-by-step.

Soft Reset:

• Hold power button 10–15 seconds.

Battery Reset:

• Turn car off.
• Wait 5 minutes.
• Disconnect negative battery terminal.
• Wait 15 minutes.
• Reconnect.

This clears many electronic glitches.

When the Radio Needs Reprogramming

If your radio was removed or battery disconnected improperly, it may need coding.

Symptoms include:

• Radio locked
• No sound but unit works
• VIN mismatch error

Dealer reprogramming may be required.
