I have successfully performed the upgrade on an AVIC-D1 using this disc. The disc includes both the software upgrade, and the new TeleAtlas data. The original image (7.28Gb) was obtained using Alcohol 120% (Media Descriptor File, MDF). It was compressed using WinRAR. You will need to decompress the MDF file to the original 7.28Gb image, then burn it to a double layer (DVD-DL) disc. This will only fit on a double layer disc. Insert disc to automatically start the upgrade. It takes about 10 minutes.
