A V8 AMG Deserves Better Than a Postage Stamp Screen
When a Mercedes SL63 AMG rolls into the B&B Audioconcepts Cardiff workshop, the bar is already set high. This is one of Mercedes’ most iconic grand tourers — 6.2 litre V8, AMG breathed on from the factory, the kind of car that commands attention wherever it goes. The plate? V8 JDY. It doesn’t get much more fitting than that.
The owner came in wanting a radio upgrade. Now for most cars, a 7″ branded Kenwood would be our standard recommendation — clean, quality, does everything it needs to. But this customer had a specific vision. He wanted 9 inches. He wanted flush. And he absolutely did not want a cheap eBay fake radio going into a car worth this much.
Luckily, we had the right Kenwood unit. And we found a way to make it work perfectly. The result is a 9″ Kenwood sitting flush in that iconic curved SL centre console — looking like it could have come from the factory floor in Stuttgart.
On a car like this, there is no room for compromise. Professional-grade equipment. Professional installation. That is the only option.
Why the Mercedes SL Is One of the Most Challenging Radio Installs
Let’s be straight about this: fitting an aftermarket head unit to a Mercedes SL (R230) is not a straightforward job. It is not something you attempt without proper preparation, experience and the correct interfaces. Several things make this particular installation genuinely difficult.
The Strip-Out
Removing the original COMAND unit from the SL’s curved centre console is a job that has reduced experienced installers to frustration. The console design means panels must come out in a precise sequence — get it wrong and you risk cracking expensive, irreplaceable trim pieces that are no longer available new from Mercedes. Patience, the right trim tools and a deep familiarity with Mercedes interior architecture are essential.
Four Types of Steering Controls
The Mercedes SL R230 has four distinct types of steering wheel control functions — telephone controls, audio controls, cruise control and additional AMG-specific functions — all routed through the CANBUS system. Retaining all of them when fitting an aftermarket unit requires a specific multi-function steering wheel interface that understands exactly how Mercedes maps each button. Without it, you lose functions the customer relies on every single day.
The 9″ Flush Fit Challenge
The SL’s centre console has a distinctive curved, organic shape. Factory COMAND units are built to that exact profile. Fitting a larger 9″ aftermarket unit flush — with no visible gaps, no misaligned trim, no aftermarket appearance — requires a vehicle-specific fascia adapter that correctly bridges the dimensional difference between the factory aperture and the new unit. Finding one that works correctly with a 9″ Kenwood for this specific SL generation took specialist knowledge. That knowledge is why this car came to Cardiff.
The Kenwood — Professional Grade. Not eBay.
The customer was absolutely right to insist on a genuine professional-grade unit. A car like the SL63 AMG attracts a certain category of cheap aftermarket product — units that look impressive in a listing photograph and perform disappointingly the moment they’re powered up. Unreliable Bluetooth. Touchscreens that barely respond. Build quality that doesn’t last a Welsh winter.
The Kenwood unit we fitted is a genuine JVC Kenwood product — built to the standards that Kenwood have maintained for decades as one of the most trusted names in car audio. Wireless Apple CarPlay. Wireless Android Auto. Bluetooth 5 for hands-free calls and audio streaming. A large, bright, highly responsive capacitive touchscreen that behaves exactly as it should. This is what a V8 AMG deserves in its dashboard.

- ▶Wireless Apple CarPlay
- ▶Wireless Android Auto

The factory COMAND unit had a screen barely bigger than a credit card.
The SL63 AMG now has a 9″ Kenwood sitting perfectly flush. Wireless CarPlay. All controls working. Customer over the moon.

Why Your Mercedes AMG Needs a Specialist — Not a Generic Fitter
One Wrong Move and Irreplaceable Trim Is Gone
The SL’s centre console strip-out is one of the most stressful in the Mercedes range. Panel clips that have been there for 15+ years, trim pieces that are no longer available new, wiring harnesses that don’t tolerate rough handling. We’ve done it before. We know the sequence. That experience protects your car.
You Don’t Lose a Single Button
The SL63 AMG’s four steering control types require a specific multi-function CANBUS interface correctly configured for this generation of Mercedes. A generic fitter with a generic adapter loses half those controls. We retain every single one — because we use the right interface and know how to configure it.
Kenwood. Not a £60 Android Unit From a Marketplace.
Cheap Android units look attractive until they’re in the car. Then the Bluetooth drops. The screen lags. The CarPlay connection is unreliable. And six months later the customer is back with problems. A genuine Kenwood unit from B&B Audioconcepts in Cardiff costs more and lasts indefinitely.
SL63 AMG. Rolls-Royce Wraith. Porsche. Alfa 4C. Jaguar XKR.

FAQ — Mercedes Radio Upgrade Cardiff
Can I add Apple CarPlay to my Mercedes SL without losing steering controls?
Yes — with the correct multi-function CANBUS steering wheel interface and a compatible head unit such as the Kenwood we fitted here. All four types of steering controls on the SL R230 can be retained and fully operational through the new unit. B&B Audioconcepts in Cardiff have completed this installation and understand the specific interface configuration required.
Will a 9″ screen fit flush in a Mercedes SL R230?
Yes — with the correct vehicle-specific fascia adapter. The SL’s curved centre console requires a precision-fit adapter that bridges the dimensional difference between the factory aperture and a 9″ double-DIN unit. Without the correct adapter the result looks aftermarket and poor. With the right parts and expertise the fit is indistinguishable from factory.
Why not just use a cheap Android radio from eBay?
On a prestige vehicle the cost difference between a genuine Kenwood and a cheap unit is small relative to the overall value of the car — but the quality difference is enormous. Cheap units suffer from unreliable Bluetooth, laggy touchscreens, and short operational life. A genuine Kenwood from B&B Audioconcepts Cardiff is backed by manufacturer warranty and will still be working perfectly in ten years.
