As for what everyone wants to know about "What format is needed for car music?" The relevant content is introduced below:

Car music needs to be in MP3 format:

1. After downloading your favorite songs or music on your computer, be sure to convert the video format. In addition to supporting MP3 format, car navigation systems generally support VCD, SVCD, DVD and some AVI and MP4 formats. Other formats, such as network streaming media formats MKV, FLV, RM, RMVB, etc., generally need to be converted with a format conversion tool before they can be played. (Of course, the video resolution should match the resolution supported by the navigation screen. If it is too high, the playback will not be smooth or cannot be played);

3. Copy the songs or music to the USB flash drive and insert it into On the USB port of the navigator; the navigator will usually automatically recognize and play it. If it cannot play automatically, you can enter the main interface of the navigator, find the USB icon, and click it to play.
