Sony XAV-W650BT is a decent double DIN (Duetch Industri Normen) car head unit with DVD player. It has all the functions you need: radio, USB, AUX, Bluetooth, NFC, DVD/VCD player, steering control support, reverse camera support, etc.
It is able to play 3 types of multimedia files in a USB thumb drive: MP3 music, JPEG photo, and XVID/MP4 video.
Playing MP3 music and viewing JPEG photo is pretty straightforward, but playing video file might need some conversion work done to its compatible format, as it will face difficulty playing video that exceeds its maximum supported video resolution of 720x576. It also requires the video to have compatible codec and frame rate.
The conversion can be performed using a free software called Freemake Video Converter.
You need to convert the video file into MP4 format, with the following custom settings:
- Frame size: 720x576
- Adjustment: Auto
- Video codec: MPEG4
- Frame rate: 30 fps
- Audio codec: AAC
- Bitrate: maximum 4096 kbps
Even if your source file is already in MP4 format, it might not work well with the head unit if the setting is different from the above. Therefore, conversion is still required to ensure it will work well.
Now, you can run your conversion and put your favourite music videos, movies (MV), recorded TV programmes, etc. into a USB thumb drive that can be played in your Sony XAV-W650BT or similar head unit in your car.
