Thank you for your advice. I know the AVIC-HD1BT is the european version of the AVIC-Z1. It would be perfect to make a 1:1 copy of the harddrive. And i asked Pioneer to help me but Pioneer told me they cant help me or i mean, they dont want to help me :roll: AVIC-Z1 is for U.S and not for europe but the european model is very expensive ($3000 an more) thats why i'm looking for another solution. I dont know somebody with a AVIC-HD1BT
