#2. Sony XAV-AX4000 – Best Single DIN Wireless CarPlay Radio

Sony XAV-AX4000

Sony XAV-AX4000

This head unit is best for those whose car has a single DIN dash opening. This stereo offers 7-inch touchscreen display, wireless carplay/Android Auto, built-in high power (200 watts) amplifier, Graphic EQ , backup camera support and many more features listed below.

Released in 2022, the XAV-AX4000 is one of the latest additions to Sony’s high-end car stereo lineup. And you can tell it from a first glance.

It has a 6.95-inch anti-glare WVGA resistive touchscreen. Unlike in car stereos from previous years, the screen in AX4000 has narrow bezels at the top and a row of popped-out physical buttons at the bottom. 

The overall design is shallow-depth, which helps in cable management during the installation. 

You get standard music input sources, such as satellite radio, Bluetooth (for music streaming and hands-free calling), USB, etc.

While the Bluetooth in XAV-AX4000 uses LDAC codec to stream higher bitrate music files, I still recommend the USB input as it gives the freedom to choose between several audio file formats, such as MP3, WMA, AAC, FLAC, ALAC, WAV, DSF, and DSDIFF. 

To further enhance the sound experience, there’s a 14-band EQ, balance/fader, subwoofer output adjustment, presets for different music genres (Rock, R&B, Pop, etc.), etc.

My favorite is the listening position setting, which is time alignment that allows you to sync the speaker sounds so that they all come to you simultaneously. 

If we talk about the crossover settings, you can adjust the frequencies for high-pass and low-pass filters – and their respective slopes. 

With all said, the main feature of AX4000 is the wireless Apple CarPlay and Android Auto.

Wireless CarPlay and Android Auto have eclipsed their wired versions as most car owners found WiFi and Bluetooth more convenient. 

But their main problem is that the built-in Wireless CarPlay/Android Auto comes in very few vehicles and only Flagship aftermarket car stereos.

Therefore, it’s good to see well-known brands like Sony pushing these high-end features into their midrange products. 

Rear connections include a USB Type-C input, rear camera input, SiriusXM input, mic input, steering wheel adapter input, etc. 

Lastly, the AX4000 is compatible with the iDataLink maestro interface, which helps you installing the head unit in cars where the stock radio is integrated with other vehicle systems (such as climate control system).
