I cant give a solid answer on that one because I bought my AVIC off Ebay and I know some stuff was already done to it because when I went to do the motion bypass it was already done. However it still had the stock HDD and (dont no one shoot me) but I bought a 60Gb Z3 upgrade HDD (MK6034GAX) off Ebay for $80. I bought it after much reading and learning what all I needed. It had the Z3 maps, 08' firmware, Gracenote and Bluetooth upgrades so I guess so.
