AVC = Automatic Volume Control
- As the car goes faster, the radio gets louder. As the car goes slower, the radio gets quieter. It "keeps" whatever perceived volume you want. It works most of the times...but some have found it to be buggy.
COMP = Compile (I think)
- It's like a sound compiler that helps even out songs...mainly for burned CD's I've found. Sometimes, the tracks you burn onto a CD might be louder/quieter than the track next to it. So, it helps to "even out" the songs.
