RetroSound Traffic DIN Radio for 1980-1993 Porsche 928

The RetroSound Traffic is the premier radio solution for Modern Classics, designed specifically for European vehicles with factory Single DIN openings. Inspired by the functional OEM styling of the late-1980s through the mid-1990s, the Traffic provides a period-correct look for BMW, Porsche, and Mercedes-Benz interiors.

Unlike standard aftermarket decks that look out of place, the Traffic features a low-profile face, subtle push-buttons, and a variable-color display to match your factory dash lighting perfectly. Its understated design makes it an ideal upgrade for enthusiasts looking to preserve the authentic aesthetic of their dashboard while adding modern audio capability like Bluetooth® connectivity and USB inputs.

Part of the RetroSound DIN Solutions lineup, the Traffic is engineered for easy installation without costly dash modifications. The modular radio motor system allows you to choose the feature set that best fits your driving style, ranging from essential classic car stereo functionality to advanced app-based control on select radio motor configurations.

Whether restoring a daily driver or completing a high-end Modern Classic build, the RetroSound Traffic Radio delivers the factory look of a vintage European radio with the performance and flexibility of a modern retro-style stereo.
