About the RetroSound GP-M4DAB-296
From our tech experts at CEN
The RetroSound Grand Prix Motor 4 (GP-M4-296) is a DAB+/AM/FM Bluetooth car stereo designed for 1980s Mercedes, BMW and Porsche vehicles. It features paddle-style controls, an adjustable 32,000-colour display and a 25W RMS x 4 MOSFET amplifier. Bluetooth 5.0, dual rear USB ports, dual RCA pre-outs and a dedicated subwoofer output are all included.
Who it suits
This suits owners of 1980s Mercedes, BMW or Porsche who want DAB radio and Bluetooth without altering the dashboard's original appearance. Those with a 1960s or 1970s classic should consider the RetroSound Europa Motor 4 instead.
Our tech experts advise
RetroSound uses a modular design, so some assembly is required before fitting. The unit is compatible only with 12V negative-earth vehicles. A vehicle-specific DIN kit (number 296) is included in the box. Bluetooth 5.0 pairs with both Apple and Android devices. Installation is priced per vehicle; see our car audio installation page for details.

Frequently Asked Questions
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.
Q: Does the Grand Prix Motor 4 have DAB radio?
A: Yes. The Motor 4 has a built-in DAB/DAB+ tuner as well as an AM/FM RDS tuner with 30 presets.
Q: Which cars is the RetroSound Grand Prix designed for?
A: The Grand Prix face is styled to suit the interiors of 1980s Mercedes, BMW and Porsche vehicles. A 296 DIN kit is included for a factory-like fit. Contact CEN with your vehicle details to confirm fitment.
Q: How many USB ports does it have?
