Choosing car accessories: a practical guide to safety, comfort and maintenance

A good set of car accessories can make everyday driving easier. Think of a CarPlay screen for navigation, a dash cam to record your journeys, a phone holder for hands-free use or a compact emergency hammer. However, there’s a wide range to choose from, and product claims aren’t always easy to compare.

The most common buying mistakes stem from three pitfalls:

  • Lots of features, few verifiable details: terms such as “smart”, “professional” or “safe” don’t tell you much without specifications such as resolution, connections, materials and dimensions.
  • The wrong compatibility: an accessory may appear suitable for every car, but still not fit a particular mirror, 12V socket, phone or vehicle.
  • Incorrect use: a car window squeegee can cause scratches if there’s sand on the surface. An emergency hammer isn’t suitable for every type of car window, and sealing tape won’t stick well to a damp surface.

Which specifications should you pay attention to?

1. Check the fit, power supply and connection

When choosing electronic car accessories, start by checking how they connect in practice. A portable CarPlay screen, for example, runs from a 12V-24V connection. This makes it suitable for many cars, SUVs, vans and lorries, but you should also check that the mounting position won’t obstruct your view.

For wireless Apple CarPlay and Android Auto, you’ll also need a compatible smartphone and a correctly paired Bluetooth and Wi-Fi connection. Check the audio output too: some screens use Bluetooth, while others use an FM transmitter, AUX cable or built-in speaker. A good car phone holder should also stay securely in place on the dashboard, windscreen or mirror mount.

2. Look beyond the headline numbers

A high camera specification doesn’t tell you everything. When choosing a dash cam, look at:

  • Front and rear cameras: check the resolution of each camera, for example 4K at the front and 1080p at the rear.
  • Viewing angle: a 140-degree angle captures a wide view, but may cause more distortion around the edges.
  • Storage: loop recording overwrites older files. A supplied 64GB TF card is handy, but check whether the system supports a larger card.
  • Night-time and weather conditions: claims about clear footage come from the brand’s product information and aren’t a guarantee for every lighting condition.

With a reversing camera, cable routing is important too. The camera needs to be securely fitted, and the cable must not get in the way of opening a tailgate or loading area.

3. Materials and use affect how long a product lasts

For car care products, the material and instructions for use are just as important as the price. A car window squeegee with a soft silicone blade is designed for smooth glass and paintwork, but only after sand and dirt have been rinsed away. Scraping a dry surface can cause scratches.

When using car wash products and car wax, the surface should be clean and dry. According to the manufacturer’s product information, the carnauba wax mentioned forms a protective layer, but how long it lasts depends on preparation, weather conditions and use. Treat “up to six months” as a product claim, not a guaranteed result.

For waterproof butyl tape, the surface must be dry and free from grease. According to the product information, TAPEBEAR tape is 100 mm wide and 5 metres long, and is designed for sealing applications including motorhomes, windows, boats and roof edges. Leave the applied tape undisturbed for 24 hours, as instructed, and don’t use it as electrical insulation.

Handy additions for maintenance and visibility

For everyday care, you can use a silicone car window squeegee after thoroughly rinsing the car. According to the product information, the compact 30 × 9,5 cm design is suitable for smooth windows, mirrors and paintwork. Don’t use it dry or apply too much pressure.

A blind-spot mirror can improve your view alongside the car. Use a convex mirror like this as an aid only: the distortion can make distances look different. Always check for yourself when changing lanes, and continue to use your regular door mirror.

For upholstery stains, an interior car cleaner or spot cleaner is more useful than a general-purpose cleaner. Test cleaning products on an inconspicuous area first, and follow the care instructions from the upholstery manufacturer.

Frequently asked questions about car accessories

Which car accessories are useful for an older car?

A portable CarPlay screen, car phone holder, dash cam and reversing camera can add new features without replacing the original infotainment system. Check the power supply, mounting position and audio connection beforehand.

How can I prevent scratches when washing my car?

Rinse away all sand and loose particles first. Then use a clean, soft cloth or silicone squeegee on a wet surface. Avoid scraping when dry, and check that the car wax is suitable for your type of paintwork.

Where should I keep an emergency hammer in the car?

Keep an emergency hammer with a seatbelt cutter within easy reach, for example in a door pocket or securely fitted centre console. Don’t leave it loose in the boot, as you may not be able to reach it quickly enough if a door is blocked.
