Burned the file to the disk popped it into my brand new AVIC Z2. It was recognized as a CD Rom. Pressed the Map button. After only a few seconds I get a mssage stating that the "...Disk is already updated" with an "Ok" button below it. After clicking the "Ok" button, the screen returns to the map and nothing else happens. I still get the parking brake wiring message after the reset. Help.
