Your car is three, five, maybe eight years old. It runs well, but its central screen looks like a phone from 2015. Blind spot sensors were not available on your model. High-tech innovations for cars are no longer just for new vehicles: a new generation of accessories allows you to modernize an existing vehicle without going through the dealership.
Camera and sensor retrofit: modernizing an older vehicle with current driving aids
Have you noticed that recent cars automatically display the rear image when reversing? This feature, now common in factory models, is absent in a large portion of the vehicles on the road. The gap between the ADAS (Advanced Driver Assistance Systems) equipment of new models and that of older vehicles fuels a rapidly growing market: rearview camera and blind spot sensor retrofit kits.
According to a market report on automotive accessories published by Mordor Intelligence in 2026, rearview camera and parking sensor kits are among the fastest-growing accessory categories. The reason is simple: features like adaptive cruise control with lane keeping are still very rare in the current fleet, prompting drivers to equip themselves.
Installing these kits does not require deep modifications to the vehicle. A standard rearview camera kit attaches near the license plate and transmits the image to a dedicated screen or the interior rearview mirror. Blind spot sensors stick onto the rear bumpers.
The safety gain is comparable to that of a recent model, for a fraction of the price. On auto-hightech.fr, this type of equipment represents a growing share of the offerings available to drivers who want to customize their car without replacing it.
CarPlay and Android Auto dongles: transforming the original car radio into a connected system
Another recurring frustration concerns the multimedia screen. An infotainment system delivered in 2018 does not support wireless Apple CarPlay or Android Auto. Replacing the entire car radio is expensive and can sometimes cause compatibility issues with steering wheel controls.
The solution that has emerged over the past two years is infotainment retrofit dongles and hubs. These small boxes plug into the USB port of the existing car radio. They convert a wired CarPlay connection into a wireless one or add CarPlay/Android Auto to a system that did not have it at all.
What to check before buying a dongle
- Compatibility with the original multimedia system: not all car radios recognize these adapters, especially models older than 2016
- Connection type (5 GHz Wi-Fi or Bluetooth): a 5 GHz Wi-Fi dongle offers lower latency and smoother display on the screen
- Firmware update management: the best dongles receive regular patches that improve stability and add support for new vehicles
The market also offers complete Android car radios with touch screens, designed to replace the original unit. These solutions are better suited for vehicles whose multimedia system is too old to accept a simple dongle.
Tinted windows and protective film: customization, thermal comfort, and safety
Why does this choice come up so often when talking about automotive customization? Because tinted windows affect three aspects at once: exterior design, thermal comfort inside, and occupant protection.
A quality solar film significantly reduces heat in the cabin during summer. Less heat means less air conditioning, resulting in lower fuel or energy consumption. In an electric vehicle, this difference translates directly into a few extra kilometers of range.
Regarding regulations, France allows the installation of tinted films on rear windows and the rear windshield but prohibits any modifications to the windshield and front side windows beyond a certain light transmission threshold. Before having a film installed, check that the installer complies with this constraint to avoid rejection during the technical inspection.
Body protection films: beyond aesthetics
PPF (paint protection film) protects the paint from gravel chips, parking micro-scratches, and UV rays. The recent innovation in this area is the self-healing capability of certain high-end films: a superficial scratch disappears under the heat of the sun or a simple wash with hot water.
Dashcam and connected OBD device: monitoring and documenting every trip
Installing a dashcam is nothing new. What has changed is the image quality and built-in functions. Recent models record in very high resolution, automatically activate recording in case of a collision (even with the vehicle parked), and store the footage in the cloud.
The connected OBD device plugs into the vehicle’s diagnostic port. It provides real-time data such as instant consumption, engine fault codes, or battery status. Combining a dashcam and an OBD device provides a complete vehicle history, useful in case of insurance disputes or to track the wear of mechanical components.
- Front/rear dashcam with built-in parking sensor: it monitors the vehicle even when the engine is off, thanks to a permanent connection cable
- OBD device with mobile app: preventive maintenance alerts go directly to the driver’s phone
- Combination of both: some recent dashcams integrate OBD reading and overlay GPS speed and engine data on the video
The trend for safety-conscious drivers is to centralize this information in a single app, rather than juggling between three different interfaces.
High-tech automotive equipment is no longer limited to what the manufacturer provided at delivery. Sensor kits, infotainment dongles, technical films, connected dashcams: each well-chosen accessory extends the useful life of a vehicle while improving comfort and safety on a daily basis. The most reliable selection criterion remains compatibility with your specific model, not the marketing promise on the packaging.
