When playing a CD/mp3 CD if i select the random option to play a random song it never works. Do you really have to play the whole song and then it picks a random song?? That really sucks if so. On my old alpine you could keep going to the next song and each time it would be random.

Also, in the cd settings there is a button for "comp" what is this? It has settings like... comp1, comp2... etc.. whats this?

That would be correct. The song has to end for the avic to randomly do another song.

Compression. short easy answer, keeps the volume the same for different frequencies.
