Description
Control & Operation
Enjoy seamless control with two convenient options:
- Factory System Integration (Coding Required): Our system includes a control unit that integrates directly with your vehicle’s OEM software. After professional coding to activate the factory menu, you can:
- Control fragrance intensity (Levels 1-3).
- Activate and deactivate the Negative Ion system.
- Use “Hey Mercedes” voice commands to manage the system.
- Mobile App Control (No Coding Needed): If you prefer to avoid vehicle coding, simply use our dedicated smartphone app to power the system on/off and adjust fragrance intensity with ease.
To use: Just place the fragrance bottle onto the magnetic base inside the unit, and it will automatically lock into place. Close the armrest box, and the system is ready to go.
Installation

Installation-video of W177 A-Class:https://youtube.com/shorts/M4wASTfrXKE
The installation process is identical to the genuine OEM part
- Aroma Generator: Aroma generator: installed in the glove box of the co-pilot passenger seat
- Important Note for some like W205/X253 Models: For certain models, such as the C-Class (W205) and GLC (X253), the factory glove box does not include a pre-cut slot for the fragrance system. A space must be manually cut to allow the glove box to close properly. If you prefer not to modify the original component, you can order a replacement glove box assembly that already includes the cutout

Shipping
- Due to international shipping restrictions on liquids, we do not include fragrance oil
We highly recommend purchasing a genuine Mercedes-Benz fragrance bottle locally. All official bottles are compatible with our system. Alternatively, you can fill the included bottle with any high-quality fragrance oil of your choice, giving you unlimited options
Performance & Usage Notes
- Longevity: Based on official Mercedes-Benz standards, one bottle of fragrance lasts for approximately 160 hours. With an average daily use of 2 hours, a single bottle can last 3-5 months.
- Diffusion Time: The fragrance will typically fill the entire cabin within 10-40 seconds after activation.
- User Experience: The perceived scent strength can vary based on factors like the vehicle’s interior size, individual sensitivity to smells, and even allergies or nasal congestion. Lighter, fresher scents will naturally appear more subtle than heavier fragrances
