I do not have an auxilary input on my head unit so i am currently running a FM mod to my 20Gig Jukebox (while i save for a new head unit). Sound is good some days and bad some days. Auxilary input is the way to go but if you have to then go with the fm mod there are a few adjustments to get rid of most of the hum on the fm mod and also in the player itself. Another thing, recording at a higher bit rate is important when using in a vehicle because you hear the full array of sound. I haven't used a cd in over a year.
