These are auto-CD-MP3 receivers (new 2004 year models).
They have a new firmware, which understands ID3 upto v2.4, and the manual says "you may encounter problems playing a high-bitrate content such as 320 Kbps mp3"
Has anyone tested which files work and which are not, and the best lame settings for this line of Sony auto mp3-receivers?
I'm particularly intersted if -alt-preset-extreme works without quirks.
