Does anyone have any recommendations?

 

There has been a lot of discussion on here, recently, about this: http://www.crutchfield.com/App/Produ...PA11NIS&tp=120. Not sure exactly if it will work with the 02-03 6cd in dash changer, but it definitely works in the 00-01's with external cd-changer port. Plays on 'disc 6' through the changer function.
Check out this thread from the 5th gen section, it has some more info: http://forums.maxima.org/showthread.php?t=557954
