I think the OP's problem might stem from the fact that his original CD is a compilation made by himself so won't be tagged or recognised as a commercial album would be. Really over my pay-grade but I think he might need a more powerful audio-editor such as Audacity, but that's a fairly big learning curve.
Hi Clive
Ive played around tagging one of my albums with Kid3 on linux and it's gone OK the only problem I'm left with is that I can't display the album title maybe I need different software !

Kid3 looks like the right tool to me.
Rob (Grindstone Cowboy) said 'Regarding your original question about why the information was not displayed in your car, I have found in the past that car systems use the ID3v1 tag (which holds basic info like track title, artist, album, etc.), rather than the expanded ID3v2 tag (which holds the same plus more, like lyrics, publisher, cover art, etc.) – the above software can copy the relevant ID3v2 tags into the ID3v1 'space' which often fixes the issue. Although I suspect more modern cars should be able to cope with either.'
Trying Kid3 on my 'Ace of Spades' example produces the same answer as VLC, except Kid3 confirms the information is stored in an ID3v1 tag. Also, Kid3 allows more tags to be added:

Note in the screenshot above that Tag 1 is labelled 'ID3v1.1' and Tag 2 is blank (ie not set),
Clicking the 'From Tag 1' button populates Tag 2 by copying Tag 1, and the second tag is labelled ID3v2.3.0

This would fix the problem described by Rob and is worth a try.
The car player gets Album and other display information by searching for tags. If it can't find a tag it can decode, it just plays the track with blank information. I guess the problem is Rob's wrong tag type, or maybe something silly like illegal characters in the text stored in the tag. (Try deleting the text and retyping it.)
'illegal characters' is a complicated subject because many programs are multi-national, supporting non-latin alphabets as well as different currency symbols, umlauts and other complications. It's complicated and chaos ensues when an unrecognised character from one domain escapes into another. Small embedded systems like media players are often limited compared with Linux, Window and Apple which are all full-throttle multi-lingual, which opens the door to mistakes.
