It’s pretty clear that EVs and software defined vehicles (SDVs) go hand-in-hand these days, and while Tesla paved the way with the Model 3 back in 2017, Rivian, Lucid, and Chinese manufacturers quickly followed. The legacy car manufacturers are taking a while longer to get on board, but are finally catching up. Companies like Hyundai Motor Group, General Motors, BMW, and Mercedes-Benz are starting to launch full SDVs.

SDVs for the win

SDVs are cars with functions and features that are primarily enabled through software and can improve over time via over-the-air (OTA) software updates. I’m not just talking about updating navigation or infotainment, here. Thanks to their zonal architecture, full SDVs use a holistic approach to software updates where every hardware module can be updated OTA, which enables diagnostics and even recalls without a dealer visit.

The cynical view is that SDVs allow greedy car manufacturers to extract revenue from customers via needless subscriptions, but that's short-term thinking. When done right, there are many benefits to SDVs. Companies like Rivian and Tesla issue free monthly OTA updates to fix bugs and add new features to their EVs, to the delight of their customers, while only charging an optional subscription for higher data connectivity and ADAS tiers.

SDVs go beyond EVs

What happens when you extend SDVs beyond EVs to hybrid and combustion vehicles? A few weeks back, I visited Mercedes’ factory near Tuscaloosa, AL, where the company manufactures most of its global SUVs, to get a first look at the refreshed GLE and GLS SUVs. Beyond more powerful engines and the usual mid-cycle cosmetic upgrades inside and out, these SUVs are Mercedes’ first hybrid and combustion SDVs. Well, almost.

Unlike their predecessors, the 2027 GLE and GLS run the company’s MB.OS across all four domains — infotainment, automated driving, body & comfort, and driving & charging — just like Mercedes’ first full SDVs, the all-electric CLA and GLC. Previously, MB.OS was only implemented for navigation and infotainment, like in the current E-Class sedan and wagon. As such, those cars weren’t SDVs. But there’s a catch.

Mercedes notes, however, that “while all of these vehicles leverage MB.OS principles and a domain-oriented software architecture, the underlying hardware, communication systems, software capabilities, and OTA deployment approaches vary by vehicle platform.” As such, the refreshed GLE and GLS, while only partial SDVs, are closer to full SDVs than any other hybrid or combustion car before them.

The 2027 GLE and GLS feature Mercedes’ pillar-to-pillar Superscreen as standard, which consists of three 12.3-inch displays (driver, center, and passenger) behind a single glass surface, and includes a selfie camera for video calls (when stopped) and for selfies, naturally. Video calls require apps like Zoom, which you can download from Mercedes’ own app store. A 3D instrument display and head-up display are available as an option.

Like the all-electric CLA and GLC, the refreshed GLE and GLS feature a generative AI-powered voice assistant which uses OpenAI’s ChatGPT4o, Microsoft Bing Search, and Google Cloud’s Automotive AI Agent (for navigation) — depending on context. The MBUX Virtual Assistant can handle a whole range of natural language requests, from adjusting the climate and music to navigation and even general knowledge queries.

Mercedes’ MB.Drive Assist Pro, the company’s NVIDIA-powered point-to-point level 2+ advanced driver assistance system (ADAS), which launched on the all-electric CLA and GLC, is coming to the 2027 GLE and GLS, first in China, then in the US later this year. This ADAS is similar to Tesla’s ill-named full self-driving (FSD), but in addition to using ten cameras, it also uses five radar sensors and twelve ultrasonic sensors.

In all, the refreshed GLE and GLS show that drivetrain variations aside, it’s possible for all-electric, hybrid, and combustion vehicles to reach parity as SDVs when it comes to infotainment, navigation, comfort, and ADAS. Let’s hope that Mercedes fully embraces this exciting new technology and follows in Rivian and Tesla’s footsteps by releasing free monthly OTA updates to fix bugs and add new features to these new SDVs.

SDVs for all

What’s even more important is that SDVs are starting to extend beyond EVs and luxury cars. Manufacturers like Hyundai Motor Group are launching more affordable hybrid and combustion vehicles that are SDVs. The zonal architecture used by SDVs makes cars inherently less expensive to manufacture since it requires fewer hardware modules and much simpler wiring harnesses (less copper means less cost and less weight).

The South Korean Grandeur sedan and Europe-bound IONIQ 3 SUV are Hyundai’s first proper SDVs. Both cars run the company’s new Android Automotive-based Pleos Connect navigation and infotainment platform, and include Hyundai’s App Market and large language model (LLM)-powered Gleo AI voice assistant. Pleos Connect, the App Market, and Gleo AI will also be coming to Hyundai Motor Group’s future Kia and Genesis cars.

Right now, most of the affordable full SDVs being developed outside of China are EVs. Ford is working on its Universal Electric Vehicle (UEV) SDV platform which will initially underpin an all-electric small truck priced around $30,000. Volkswagen’s upcoming ID.1 city car, destined for Europe and priced below €20,000, is the company’s first SDV. Its zonal architecture and software stack are a direct result of VW’s partnership with Rivian.

Hopefully, these new EV-first platforms can also be adapted to manufacture more affordable hybrid and combustion SDVs. Because while I believe that the future is all-electric, hybrid and combustion vehicles will be sticking around a little while longer, at least here in the US. And considering the cost and feature benefits of SDVs, it would be a shame if manufacturers didn’t deploy this technology across all their upcoming vehicles.

My takeaway

Between 2018 and 2024, I owned two Tesla Model 3s, so I was able to enjoy the benefits of SDVs firsthand. There’s something utterly wonderful about finding an OTA software update waiting in your car every month, ready to deliver new functionality for free. Rivian aside, I have missed this on every other EV I’ve driven since, and because of this positive experience, I will forever associate SDVs with EVs.

But as Mercedes has shown with the refreshed GLE and GLS SUVs, the benefits of SDVs also extend to hybrid and combustion vehicles. SDVs allow the company to provide a consistent and modern user experience across its entire lineup, regardless of drivetrain. Not to mention, SDVs reduce costs and complexity for all manufacturers. As such, I’m looking forward to SDVs becoming the norm for more cars going forward.

Modern cars are becoming increasingly good at reminding drivers about speed limits, upcoming safety cameras and potential hazards. So much so, driving is now soundtracked by a cacophony of irritating bleeps and bloops.

But unless you've bought something new in the past few years, there's a good chance your car is missing many of these features altogether.

Even if it isn't, many factory-fitted systems are far from perfect. Speed camera databases aren't always comprehensive, speed limit recognition can be caught out by temporary signs, while built-in alerts often arrive too late or are buried beneath layers of infotainment menus.

That's where dedicated speed camera detectors come in. These discreet dashboard companions warn of fixed cameras, average-speed zones, changing speed limits and road hazards without requiring you to constantly glance at a navigation or smartphone screen.

Unlike apps such as Google Maps or Waze, most of these gadgets are designed to fade into the background. Once paired with your phone, they quietly monitor your journey, without the need to plumb a destination into the navigation, only piping up when there's something worth knowing about.

Some even integrate with Apple CarPlay and Android Auto, playing alerts through your car's speakers while leaving your preferred navigation app to handle directions.

It is worth noting that the tested and models (below) are available to purchase and are perfectly fine to use in the UK and much of Europe, but aren't widely available in the US and other regions. These are five of the best dedicated speed camera detectors we'd recommend.

1. Ooono Co-Driver NO2

• Price: £69.99 / $95 / AU$143
• Rating: 5/5

Design

The Ooono Co-Driver NO2 sets the benchmark for one simple reason: it makes almost every rival feel unnecessarily complicated.

Designed in Denmark, the compact puck-shaped device looks more like a premium smart home accessory than a piece of automotive hardware. A subtle aluminum outer ring, bright wraparound LED indicator and minimalist styling mean it blends neatly into almost any dashboard without drawing attention to itself.

Its mounting system remains one of the smartest available. Rather than relying on a large adhesive pad, Ooono supplies two tiny magnetic mounting points with discreet 3M backing. Once installed, the device simply snaps into place magnetically and can be removed in seconds for charging or swapping between vehicles. An optional sun-visor mount also allows it to be positioned completely out of sight while remaining within easy reach.

Unlike the original Co-Driver, the second generation features a rechargeable battery that lasts around a month between charges and tops up via USB-C, eliminating the need for disposable batteries or permanent power cables.

Setup

Getting started takes a few minutes. Download the free Ooono app, pair the device over Bluetooth and grant the necessary permissions. Once configured, it automatically wakes whenever it detects your smartphone nearby, meaning there's very little to think about before setting off.

The latest generation also adds native compatibility with both Apple CarPlay and Android Auto, allowing alerts to play directly through the vehicle's audio system while your preferred navigation app continues handling directions. It feels like a small upgrade but makes a noticeable difference during longer journeys, especially if you prefer keeping your phone tucked away.

Perhaps best of all, there are no subscriptions or premium membership tiers to worry about. Once you've bought the hardware, everything else is included. Bonus.

Performance

Fixed speed camera alerts arrive with plenty of notice, accompanied by bright LED flashes and clear audible warnings that are difficult to miss without becoming too irritating. Optional speed limit notifications can also be enabled, providing a gentle reminder whenever you creep above the posted limit.

Now, these can get annoying, but there’s plenty of adjustability and personalization within the accompanying smartphone app, so you can get blend just right.

Reporting hazards is also dead easy. A couple of button presses allows drivers to report mobile speed cameras, accidents or broken-down vehicles, while a dedicated cancel button quickly dismisses false alerts. The controls become second nature after only a few journeys and, crucially, never require you to look away from the road.

The only area where Ooono still trails the biggest smartphone navigation apps is community reporting. While its network continues to grow rapidly across the UK, services such as Waze can still provide more comprehensive reports for temporary hazards and mobile enforcement in some regions.

That said, Ooono's verified speed camera database is very good and rarely got things wrong during testing. Plus, its combination of stylish design, thoughtful ergonomics and genuinely useful alerts makes it the easiest dedicated speed camera detector to recommend.

2. Tom by TomTom

• Price: £69.99 / $95 / AU$143
• Rating: 4/5

Design

If the Ooono is the minimalist Scandinavian option, the awkwardly-named Tom by TomTom is the slightly more extrovert cousin.

The overall concept is basically the same: a small dashboard-mounted unit with LED alerts and physical buttons for reporting incidents. The TomTom device is a little larger and uses a full adhesive ring mount rather than Ooono's tiny magnetic points, which makes it feel more permanent once installed. There is no visor-mount option either, so it is clearly intended to live on the dashboard full-time.

The upside is visibility. The bright LEDs are among the easiest to spot while driving, particularly in strong sunlight, and the rechargeable battery lasts roughly a month between charges, meaning there is no need for a permanent power cable snaking across the cabin.

Build quality is decent, although the plastics don't feel quite as premium as the Ooono's aluminum-trimmed shell. Plus, there are fewer limited edition finishes like Ooono offers.

Setup

TomTom deserves credit for making the onboarding process almost foolproof. Again, it’s all handled through an app, where users create a free account, pair the device over Bluetooth and you're essentially ready to go. There are no subscription tiers, no payment details to enter and very little opportunity for things to go wrong.

The device automatically reconnects when you get in the car and, because it relies on your phone's data connection, camera and hazard information stays up to date without requiring manual downloads.

Performance

In daily use, the Tom by TomTom runs the Ooono devices surprisingly close. Fixed camera alerts are timely and accurate, average-speed zones are handled well and the visual warnings strike a good balance between noticeable and distracting.

The device also warns when you exceed the limit, using a combination of color changes and audible alerts that are difficult to ignore without becoming overbearing.

Reporting incidents is straightforward, with single and long presses assigned to different hazard types, although the button layout isn't quite as intuitive as Ooono's oversized top-mounted control. Finding the correct button by touch occasionally requires a little more finger fumbling than ideal.

TomTom's greatest strength remains its mapping and traffic data expertise. The camera database proved consistently accurate during testing, and the overall experience felt polished, reliable and refreshingly low-maintenance.

For many drivers, it will come down to a simple question: whether you prefer TomTom's brighter, LEDs or Ooono's more discreet industrial design and slick Apple CarPlay or Android Auto integration.

3. Road Angel Pure Sync

• Price: £99.99 / $135 / AU$205
• Rating: 3.5/5

Design

The Road Angel Pure Sync takes a very different approach from the puck-shaped devices above.

Instead of disappearing into the dashboard, it places a small color display front and center, showing GPS speed, speed limits and camera warnings at all times. The magnetic mount is neatly integrated with the USB-C power connection, helping to keep cable routing tidier than many older dashboard gadgets.

Unfortunately, the device still requires constant power, so there is always a cable to manage somewhere in the cabin. Build quality is also less convincing than the price suggests, with a noticeably plasticky shell and a screen that can become difficult to read in direct sunlight depending on where it is mounted.

Setup

This is, by far and away, the weakest link in the Road Angel's armor. Despite the included 12-month subscription, registration still requires payment details, which feels unnecessarily complicated when rivals simply ask you to download an app and pair a device.

Bluetooth pairing also proved temperamental during setup, requiring several attempts before the phone and hardware consistently connected. Once configured, however, the system generally behaved itself and reconnects automatically when you start the car.

Performance

Camera warnings arrive with plenty of notice, while the speed limit system is impossible to miss: the screen flashes red and the device emits a loud voice warning whenever you drift above the posted limit. In fact, the default volume is so aggressive that most drivers will probably dive into the settings menu and turn it down after the first journey.

The live GPS speed display is genuinely useful in older vehicles with optimistic analogue speedometers, although it feels less essential in modern cars that already provide accurate digital speed readouts.

Hazard reporting works well once you've memorized the controls, with incidents submitted to the Road Angel community for verification before being distributed to other users. As with all cloud-connected systems, coverage still depends on local user numbers, and Waze, Ooono and the TomTom device all remain stronger for temporary hazards in some parts of the UK.

The Pure Sync ultimately feels like a halfway house between a traditional sat-nav camera alert unit and the newer minimalist Bluetooth devices. If you value a permanent speed display and don't mind the subscription model, it remains a capable option. If simplicity is the priority, the Ooono and TomTom solutions are easier to live with.

4. Ooono Co-Driver NO1

• Price: £19.99 / $27 / AU$41
• Rating: 4/5

Design

The original Ooono Co-Driver remains available and, placed beside the newer NO2, it is immediately obvious how much the design has evolved.

The first-generation unit is noticeably smaller and arguably even more discreet, blending into the dashboard almost completely once installed. However, it uses a fixed adhesive mount rather than the newer magnetic system, making it less convenient to remove or transfer between vehicles.

It also relies on a coin-cell battery rather than a rechargeable pack, although Ooono claims around a year of battery life before replacement is needed.

Setup

As before, setup is very simple and anyone can have it up and running in a matter of minutes. The device pairs with the Ooono app over Bluetooth and then quietly runs in the background using the phone's data connection and GPS. There are no subscription fees and no complicated menus to navigate.

Performance

For the core job of warning about speed cameras, the NO1 still performs remarkably well. It uses the same Ooono camera database and community reporting network as the newer model, so alert accuracy remains strong.

What you lose are the convenience features: there is no Apple CarPlay or Android Auto integration, no rechargeable battery and no dedicated false-alert cancellation button.

For drivers who simply want reliable camera warnings in the smallest possible package, the original Co-Driver remains one of the cheapest and most discreet options on sale.

5. Snooper My-Speed Plus

• Price: £199.99 / $270 / AU$410
• Rating: 3/5

Design

After spending time with the smartphone-connected devices above, the Snooper My-Speed Plus feels like a product from a different era — and that is not necessarily a criticism.

Rather than a tiny puck on the dashboard, Snooper gives you a full 5-inch color display mounted to the windshield or dash, complete with speed readouts, camera warnings and traffic information. It looks more like a compact sat-nav than a modern Bluetooth accessory, and it occupies a lot more real estate as a result.

The larger screen does have advantages. Speed limits and GPS speed are visible at a glance, while the red-and-green graphics make it very obvious when you have drifted above the limit.

Setup

Unlike the other products here, the Snooper operates independently of your smartphone. The device contains its own GPS receiver and uses Snooper's AURA camera database, so there is no need to keep a phone connected during journeys. Initial setup is straightforward, but keeping the database current requires occasional manual updates via USB using a Windows PC or Mac.

That feels decidedly old-school in 2026, but some drivers will appreciate the complete independence from apps, Bluetooth connections and mobile data.

Performance

Once updated, the Snooper's camera coverage is excellent. Fixed camera warnings are reliable, average-speed zones are handled well and the large display provides far more information than the minimalist LED-based rivals.

The trade-off is size and cost. At £199.99, it is by far the most expensive device in this guide, requires permanent power from a 12V socket and occupies a significant portion of the windshield compared with the almost invisible Ooono or TomTom units.

For drivers who want a dedicated, easy-to-read display without relying on a smartphone, the Snooper remains a compelling niche option. For everyone else, the newer Bluetooth-based devices generally deliver a cleaner, more modern experience.

Which should you buy?

If you simply want the best all-round experience, the Ooono Co-Driver NO2 remains the device I'd recommend. Its combination of elegant design, effortless setup, strong camera database and CarPlay and Android Auto integration makes it the easiest product here to live with every day.

The Tom by TomTom runs it surprisingly close and offers excellent value for drivers who prefer bright, visible alerts from the built-in LEDs. Road Angel Pure Sync will appeal to owners of older vehicles who value the permanent GPS speed display, while the Ooono NO1 remains a brilliant budget entry point.

The Snooper My-Speed Plus, meanwhile, occupies its own category entirely. It is larger, more expensive and more old-school than the others, but its standalone GPS operation means it doesn’t blitz data on your smartphone. Regardless, it’s absolutely massive and feels OTT compared to the others.
