Yes to all. Sometimes having a good CD that you just hit a button and bam it plays, no syncing, worrying about charging/battery power, cables etc.. The USB is horrible. It has never worked in a logic I relate too, maybe Im doing it wrong but a limit on how many folders you can change whilst driving to the genral flow and user interface is habby shabby at best.
The audio quality is BEST with a CD (my experience). I know you can only have loaded, x4 CD's at one time but they are there on demand.
So this leads to my question, if I can store 100 songs on a CD that the JBL w/nav player will read I will then have 400 songs to play on demand with a click of a button and no faffing around with syncing, charging, wires etc... may sound silly but there is a method to my madness here

SO DOES ANYBODY HAVE ANY EXPERIENCE HERE or HAPPEN TO KNOW? Thank you for your suggestions!
