Do most of the connectors that plug into the cd changer allow you to choose artist, album, etc... or do you have to use playlists for playback in the car?

ALSO

Is there a cheaper option than spending around $170-$200 for something like the Neo Ion that plugs into the cd changer port? I want something that charges and alows me to still choose any song or album I want. (I have a 2002 Passat GLS w/ a monsoon stereo system)
