How does the CO-DRIVER work?

The CO-DRIVER is a community-driven device, which connects you to millions of drivers who report incidents on the road each and every day. This way, your CO-DRIVER always gives you up-to-date warnings wherever you go and helps you be one step ahead in traffic, knowing when a speed camera or road hazard is coming up.

Every warning you receive comes from someone who was just ahead of you. Whether it’s a speed camera or a road hazard, your CO-DRIVER gives you a heads-up so you can stay focused and avoid surprises.

And you’re part of that system too. With a quick tap, you can confirm or report what’s happening — helping the next driver behind you.

The OOONO CO-DRIVER comes with the OOONO app. The app is free to use, does not require a subscription, and can be downloaded from the App Store or on Google Play.  You can use the OOONO app in English, German, Danish, Italian, French, or Spanish.

What you’ll learn next:

• How warnings work - and how to confirm or report them.
• What the device connects to - and how to know it’s working.
• How the battery works - and how to keep it powered.
• Mounting tips so your device stays in place and within reach. 

Let's get into it.

Reporting, Confirming & Dismissing Warnings

Your CO-DRIVER warns you when other drivers report something up ahead — like a speed camera or road hazard. If you spot the same thing, confirming it helps keep that warning active. If it’s new, reporting it helps others. And if it’s no longer there, you might be able to dismiss it (with CO-DRIVER NO2).

How does the connection work?

Once you’ve completed the setup in the OOONO app, your CO-DRIVER connects automatically — no need to tap, switch, or open anything before each drive.

As soon as you start driving, the device wakes up and connects to the nearest phone it’s paired with. This ensures a smooth, hands-off experience every time you get in the car.

If you prefer to connect before the car starts moving, open the OOONO app on your phone — this will manually trigger the connection. Or just give your CO-DRIVER a quick shake — that works too.

You’ll know it’s connected when the CO-DRIVER flashes green and gives a short confirmation sound.

What should I know about the battery of the CO-DRIVER?

Your CO-DRIVER is designed to work silently in the background — and that includes its battery. Whether you’re using the rechargeable CO-DRIVER NO2 or the long-life CO-DRIVER NO1, here’s what to know to keep things running smoothly.

Mounting

Your CO-DRIVER should always be within easy reach — so you can tap quickly when needed. Both models are designed to stay firmly in place, without getting in your way while driving.

Below you’ll find the available mounting options for each version.

CO-DRIVER NO2 & CO-DRIVER NO2 PLUS

CO-DRIVER NO2 comes with discreet magnetic mounts, giving you a secure hold and flexible placement. The metal plates are backed with adhesive, so once you've found your spot, they stay put — while the device itself can be removed anytime.

CO-DRIVER NO1

This version uses simple adhesive strips to stay in place. You can mount it wherever it’s most comfortable for you — typically on your dashboard or center console.
