ok, i'll try ethernet since my apple has that available.

Good, it's the fastest way to get songs into the car player.

And by the way, to reply to something that was said in the crossposted version of this thread:

Paul is right, you do need player firmware version 2.0 final in order for Jemplode to work properly. So check that (from the "About" menu on the player) first. If it doesn't have it, you'll need to temporarily borrow a friend with a PC in order to apply that upgrade. You also might want to take that opportunity to install the latest Hijack while you're getting your hands dirty with the PC. You know, get it all over with once, so you only have to do the ritual hand-washing thing once.
