Using a mac, just copy the .bin file to the usb memory stick.
IMPORTANT: Don't decompress the .bin file.
Make sure the stick is formatted in a pc format. If it's not use "Disk Utility" [Applications>Utilities>Disk Utility] to erase and format as MS-DOS (FAT16). Copy the "UPD01006.bin" file to the USB stick, dont put it in any other folder. It should take about 15 seconds for the car to recognize the usb drive and software.
