Here are some of the ones our users have been enjoying the most lately:
1. Start/Stop Deactivation
Mercedes’ ECO Start/Stop system automatically shuts off the engine when you stop and restarts it when you move. While it helps reduce fuel consumption, it’s not always ideal – especially in city traffic.
With the Start/Stop Deactivation One-Click App, you can turn this feature off completely – no more pressing the button every time you start your car.
Why Mercedes drivers love it:
Smoother driving with fewer interruptions.
2. Start/Stop Memory
A useful addition when Start/Stop Deactivation is not permanent, this app remembers your last setting. If you turn it off, it stays off the next time you start your car.
Why Mercedes drivers love it:
No need to repeat the same action every drive.
3. Multimedia Startup Logo
This One-Click App lets you change the startup logo of your infotainment system, giving your Mercedes a more personalized feel every time you turn it on.
Why Mercedes drivers love it:
A subtle but premium custom touch – and great for a dramatic first impression upon turning on the engine.
4. Video in Motion
Video in Motion allows video playback while the vehicle is moving – a feature often restricted by default.
Why Mercedes drivers love it:
Keeps passengers entertained on longer trips.
5. Comfort Turn Signals Count
Ever wished your turn signal blinked more (or fewer) times? This app lets you adjust the number of indicator flashes with a light tap.
Why Mercedes drivers love it:
Improves signaling clarity during lane changes, especially on highways or in heavy traffic.
Note: The Comfort Turn Signals feature must be activated prior for this to work.
6. Scandinavian DRL
Scandinavian DRL keeps daytime running lights (DRL) on alongside your taillights simultaneously, improving visibility and giving your car a distinctive look. In some regions, this setting is even required.
Why Mercedes drivers love it:
Better visibility and a stylish lighting upgrade – especially useful in dull weather conditions.
7. Footwell Lights While Driving
Keep your footwell lights on while driving to enhance the cabin atmosphere – especially at night.
This One-Click App keeps the footwell lights always on as part of the ambient lighting system, as long as your vehicle is equipped with them.
Why Mercedes drivers love it:
Adds a more premium interior feel.
8. Multimedia Display Theme
This One-Click App lets you change your display theme, giving your dashboard a fresh visual style and allowing day and night modes depending on the model.
Why Mercedes drivers love it:
A simple way to refresh your interior without any hardware changes.
9. DRL with Turn Signal
This feature adjusts how your daytime running lights behave when signaling.
When activated, the DRL on the side of the active turn signal temporarily turns off, enhancing blinker visibility.
Why Mercedes drivers love it:
A subtle upgrade that adds contrast and a more modern lighting effect.
10. Dynamic Tachometer Mode
Dynamic Tachometer Mode enhances how your gauges behave, making the instrument cluster more responsive. With this function on, the tachometer reacts faster than the actual engine revs.
Why Mercedes drivers (and enthusiasts) love it:
A more engaging, sportier display feel.
