Add-ON DAB

Porsche Add-On DAB Systems - Digital Radio Upgrades with OEM Integration

Porsche Add-On DAB (Digital Audio Broadcasting) systems allow vehicles without factory-fitted digital radio to receive DAB and DAB+ stations while retaining the original infotainment system. Designed to integrate seamlessly with Porsche PCM or factory head units, Add-On DAB solutions deliver improved audio quality, wider station choice, and modern radio functionality without replacing the OEM setup.

Available from Design911, Add-On DAB systems provide a clean, reversible upgrade that preserves interior originality while bringing older Porsche multimedia systems up to modern standards.

What Do Porsche Add-On DAB Systems Do?

Add-On DAB units expand radio capability by converting digital broadcasts for factory audio systems.

Core Functions:

• Enable DAB and DAB+ digital radio reception
• Improve sound quality over analogue FM
• Increase available radio station choice
• Integrate with factory head units and controls
• Maintain OEM appearance and system compatibility

They offer a practical solution for modernising in-car audio without full system replacement.

Why Do Add-On DAB Systems Fail?

Add-On DAB systems rely on electronics, antennas, and signal processing that can degrade over time.

Common Causes of Failure:

• Antenna damage or poor signal reception
• Internal module or tuner failure due to age
• Wiring or connector issues behind the dashboard
• Compatibility problems with updated infotainment software
• Moisture ingress or heat exposure

Failure may result in poor reception, loss of stations, or system recognition issues.

When Should an Add-On DAB System Be Replaced?

Porsche Add-On DAB systems should be replaced when:

• Digital radio reception becomes unreliable
• Stations drop out or fail to load
• The system is no longer recognised by the head unit
• Upgrading infotainment or audio components
• Improving compatibility with newer DAB+ standards

Replacing an ageing unit restores reliable digital radio performance.
