I am only able to see 1 or 2 tag data when playing a song on my mobile or car audio system. Is it possible to see atleast 4-5 tag data information on the same?
As you already write: I think it is mainly a problem of
Even though there is also the other side:
What file format are we talking about? MP3? FLAC? WAV? something else?
Which tag versions do you have in the mp3 files? V1? V2? APE?
Which tag fields have you filled already? A screenshot of a single file's extended tags dialogue would help.
Which fields does the car player display and which would you like to see?
