If you have an old Garmin Nuvi, it has a built in MP3 Player.

However, you can only have 1,000 max MP3 files.

Solution: Use some free software to do an "MP3 merge" of the songs on an album.

If there are 10 songs on an album you will get 1 larger MP3 file with the 10 songs in it.

Put this new larger file on your Garmin thinks you only have 1 song, not the 10.

Only downside is you cannot jump forward between the songs in the album
