RetroSound Radio Traffic TRA-M4
The RetroSound® Traffic Radio is designed to replicate the style of the factory radio in your vehicle.
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.

FAQs
Q: Will this stereo fit my car?
A: Most vehicles need a fascia panel, wiring harness and sometimes a steering wheel control interface to fit a new stereo. Contact CEN with your make, model and year and we will confirm the exact installation kit needed, or browse our Connects 2 installation kits.
Q: Will I keep my steering wheel controls?
A: Yes, in almost all cases. A steering wheel control interface retains your existing buttons with the new stereo. Parts are sold separately.
Q: Does this stereo support Apple CarPlay or Android Auto?
A: Check the Specification tab, which lists smartphone connectivity for each model including whether CarPlay and Android Auto are wired or wireless on that unit.
Q: What is the difference between single DIN and double DIN?
A: DIN refers to the chassis size. Single DIN units are the traditional slim format, while double DIN units are twice the height and typically carry a touchscreen. Your vehicle's dash aperture and fascia kit determine which fits.
Q: Can CEN supply and fit the stereo?
A: Yes. CEN offers professional supply and installation from our Nottingham premises, including fascia, wiring and steering control integration. Contact us for a fitted price.
