Mercedes C-Class (W204 / S204) Android 15 Car Stereo Head Unit

Exceptional customer support

Package arrived in 2 days, beautifully boxed. I had a slight issue getting the factory sound to play, messaged SyncSonic support on WhatsApp, and they sent me a video showing exactly how to activate the AUX menu. Brilliant service.

Pure digital audio output

I bypassed the factory amp completely and used the optical TOSLINK output straight into a Mosconi DSP. The audio signal is completely pure digital with zero alternator whine. Audiophile dream.

Parktronic radar overlay is brilliant

When I put the car in reverse, the screen automatically switches to my aftermarket camera, but it also overlays a digital graphic of the car reading my original factory parking sensors. Awesome integration.

Android 15 is exceptionally stable

Running live OBD2 engine telemetry via Torque, streaming HD music, and running Waze simultaneously on the A18 PRO model. The system hasn't crashed or hung up a single time.

Solid mounting hardware

The custom bracket that comes with the screen bolts securely into the original factory mounting holes. The screen is rock solid and doesn't vibrate or shake at all over rough UK B-roads.

Highly responsive touchscreen

The capacitive glass feels premium, like an iPad. Swiping through the app drawer and pinching to zoom on satellite maps is incredibly fluid without any frustrating ghosting.

Massive 128GB local storage

Downloaded massive offline map areas for a European road trip, plus gigabytes of Spotify playlists. The eMMC storage is very fast and I still have tons of space left over.

Flawless GPS lock

The magnetic GPS receiver works flawlessly. I mounted it right underneath the plastic top-center speaker grille on the dashboard. It locks onto 15+ satellites instantly with zero dropouts.

Retains all factory car settings

I was worried I wouldn't be able to change my car's clock or interior lighting settings anymore. But because you can switch back to the original Mercedes NTG screen with one tap, absolutely nothing is lost.

A6 PRO base model is incredible value

I didn't need 4G or crazy RAM, just wanted Wireless CarPlay for my daily commute. The A6 PRO quad-core handles it perfectly. Very cheap way to get modern navigation in an older Mercedes.

Transforms the C-Class interior

The W204 pre-facelift interior aged quite poorly compared to modern cars. Slapping this massive, sleek screen on top completely rejuvenates the cabin. UI themes resemble the newer MBUX system.

Split screen is perfect on a 10.25 display

The ultra-wide aspect ratio is practically made for split-screen. I have Google Maps running on the left 70% of the screen, and my media player on the right 30%. Incredibly functional layout.

Bluetooth calls are crystal clear

Mounted the supplied clip-on microphone up near the rearview mirror. Callers say they can hear me perfectly at 70mph, the echo cancellation software on the Bluetooth 5.0 chip does a stellar job.

Installation took an afternoon

Taking the W204 dashboard apart is a bit daunting (watch a YouTube video for the air vents!), but the wiring behind the radio is strictly plug-and-play. Very rewarding DIY project.

Instant boot is amazing

I turn the ignition on my C220 CDI and the screen wakes up in literally 1 second. No annoying Android loading animations every time I get in the car. It picks up exactly where my music left off.

Zero lag with 8GB RAM

I went for the highest spec version. Bouncing between the factory NTG 4.0 menu, Apple CarPlay, and split-screen Android apps is buttery smooth. The Octa-Core processor handles heavy loads brilliantly.

4G LTE is a lifesaver

Routed the 4G SIM card slot into my glovebox. Dropped an EE data SIM in there and the car now has standalone internet. Waze gets live traffic and Spotify streams without ever needing my phone's hotspot.

Fantastic anti-glare IPS panel

Because this screen sits high up on the dash, it gets a lot of direct sunlight. The anti-reflective coating is excellent, keeping Google Maps completely visible even on bright summer days.

Steering wheel buttons work exactly as they should

The supplied CANbus harness is magic. Volume up/down, track skipping, and phone answer buttons on my steering wheel communicate with the Android interface instantly. No programming required.

The X73 PRO 360 camera makes parking effortless

My S204 Estate is quite long. Upgraded to the X73 tier and fitted the 360-degree cameras. The high-res ultra-wide display shows the top-down view flawlessly alongside my reversing angle. Highly recommended.

Harman Kardon system retained beautifully

My C-Class has the factory Logic 7 fiber optic amp. Bought the optional MOST decoder box with this unit, plugged the orange cables in, and it worked instantly. The 32-band DSP actually makes it sound better than stock.

Joystick integration is seamless

I was worried I would have to use the touchscreen for everything while driving. Thankfully, the original silver command dial on the center console scrolls through the Android menus and CarPlay perfectly. Very safe for motorway driving.

Great unit, remember to activate AUX

The system is incredibly fast and Wireless CarPlay is flawless. Just a tip for DIY installers: you must go into the Mercedes secret engineering menu to enable AUX so the Android audio plays through the car speakers. Once done, it's perfect.

Unbelievable upgrade for my W204 C63 AMG!

The original pop-up screen was painfully outdated. This 10.25-inch ultra-wide screen sits beautifully on the dash and makes the interior look 10 years newer. The fact I can still access my original AMG menus is a huge plus.
