Can music stored on Infiniti G37 hard drive be overwritten?

[ThatNewGuy]

I was taking delivery on my G37 today and my dealer couldn't confirm, but he'd been told that Infiniti's hard drive for music is one-way only, meaning you can store music, but you can't delete the music once it's saved.

I didn't get a chance to go through my owner's manual or fool around with the system to verify this.


Can anyone shed light on this?
