Choosing car accessories and electronics: a practical buying guide for every driver

An older car does not necessarily need a new infotainment system. With the right car accessories and electronics, you can add wireless CarPlay, Android Auto, hands-free calling, wireless charging or vehicle diagnostics, for example. However, not every product is suitable for every car or phone.

Many unsuitable purchases come down to three recurring pitfalls:

  • Compatibility is presented too broadly. A wireless CarPlay adapter will generally only work if the car already supports wired CarPlay. An Android Auto adapter has similar requirements.
  • A strong magnet says nothing about the mounting. A magnetic phone mount may stay firmly attached to the phone, while the clip comes loose from the air vent.
  • Extra features come with hidden requirements. A CarPlay AI Box may support apps and video, but often requires a genuine wired CarPlay connection. Some models are not suitable for BMW, Tesla or aftermarket head units.

Check these three points first

1. Connection and operating system

Before buying a wireless CarPlay adapter or Android Auto adapter, check the following:

  1. Does the car have factory-fitted wired CarPlay or Android Auto?
  2. Does the infotainment system use USB-A, USB-C or another connection?
  3. Which version of iOS or Android is required?
  4. Can the phone support wireless projection?

For example, the OTTOCAST Mini 2-in-1 Wireless CarPlay/Android Auto Adapter states that it supports many vehicles with wired CarPlay or Android Auto and requires at least iOS 10 or Android 11, according to the product information. The manufacturer also lists exceptions, including BMW, Tesla and vehicles made before the specified model generation. Always check both the product’s compatibility list and your vehicle.

A CarPlay AI Box goes beyond simply creating a wireless connection. According to the product specifications, the OTTOCAST P3 supports wireless CarPlay and Android Auto, Android 12, HDMI output and 8 GB RAM with 128 GB storage. The key requirement remains important: the car must have genuine wired CarPlay. Video apps should only be used when the car is stationary and where this is permitted under local traffic regulations.

2. Mounting, size and viewing angle

When choosing a wireless phone mount for your car, the following features matter more than a striking marketing label:

  • Does the clip fit your air vent?
  • Is the phone, including its case, not too heavy or thick?
  • Can you adjust the screen without blocking your view or the controls?
  • Does the mount remain stable on cobbled roads and speed bumps?

According to the product description, the A2C M10M-AV6S uses an N52 magnet, a metal clip with a rotating lock and 360° adjustment. The mount supports MagSafe devices and phones with a metal ring. A metal ring is therefore required if your phone or case does not have a magnetic attachment.

Cyclists and motorcyclists have different requirements. A motorbike and bicycle phone mount must fit around the handlebars, withstand vibrations and leave enough room for a protective case. According to the stated specifications, the Oxerbog mount is suitable for phones measuring 4.7 to 7 inches and with a total thickness of up to 12 mm. Larger phones with a case may have a more limited fit.

3. Charging technology and power supply

A wireless car charger is only practical if your phone supports wireless charging. MagSafe and Qi2 provide magnetic alignment for compatible devices, but a magnetic phone mount without a charging coil will not charge automatically.

Also consider the power source. A wireless car charger or FM transmitter often uses the 12V socket. Check that the adapter is suitable for your vehicle’s voltage and unplug accessories when the car will be stationary for an extended period. With a Bluetooth FM transmitter, you will also need to find a clear FM frequency. Busy frequencies can cause noise or interference.

Extra considerations for charging and everyday use

The included adapter and cable make the power requirements clearer.

When using magnetic accessories, be aware of safety warnings relating to medical devices and always follow the usage instructions.

Frequently asked questions

Does a wireless CarPlay adapter work in every car?

No. The car will generally need to support wired CarPlay already. Also check the year of manufacture, the USB connection, the phone version and any brand- or model-specific exceptions.

Is a Bluetooth FM transmitter suitable for music and calls?

Yes, provided the car radio can receive an FM frequency. Pair your phone via Bluetooth and tune the radio to the same clear frequency. Sound quality may vary depending on local radio interference and the frequency selected.

How long do car accessories and electronics last?

Service life depends on heat, moisture, vibrations, charging load and everyday use. Mount holders securely, keep charging ports clean, avoid prolonged exposure to sunlight and unplug 12V accessories when the car is not in use. Also check the warranty terms and available updates before placing your order.
