For many earlier Mercedes models, it’s the in-car technology -not the styling or performance- that shows the vehicle’s age. Retrofitting a modern aftermarket head unit like the Pioneer SPH-DA77DAB is a smart way to bring your Mercedes up to date with current infotainment features that original factory units may not offer.
We install the Pioneer unit using a vehicle-specific fascia kit that integrates seamlessly into your Mercedes dashboard, replacing the original head unit. An interface is also fitted to retain steering wheel controls for volume and phone functions.
Please note: while radio info won’t appear in the instrument cluster screen, all other vehicle data will remain visible. If your existing COMAND unit handles time/date syncing, we’ll update the coding to allow manual adjustment after removal.
For vehicles without a factory DAB aerial, we install a discreet digital antenna in the top-left corner of the windscreen, providing clean, reliable reception without disrupting the interior.
This retrofit gives you full Apple CarPlay and Android Auto compatibility, allowing real-time navigation, voice control, and access to your favourite apps, all via the responsive Pioneer touchscreen interface.
Key Features of the Pioneer SPH-DA77DAB:
- AM/FM/DAB Radio
- Bluetooth Telephone & Audio Streaming
- Wireless Apple CarPlay
- Wireless Android Auto
- Touchscreen Operation
