I'm now seeding the torrent I made from R32Viper's SD Card files for the Z110BT update that Pioneer recently released. It is almost 3 gigabytes so please be patient, and SEED.
Note: I had to rar the torrent file since the forums do not allow the .torrent extension. Use winrar to open on Windows or UnRarX if you are using a Mac. Then, use the Bittorrent client of your choosing to download the upgrade files.
EDIT: Forum member ShortFuse has cracked this update, see his thread here for details.
EDIT 2X: If you are not already using it, please consider uTorrent to download this torrent. Members have been having issues with Azureus/Vuze but uTorrent seems to work just fine. Also, my seedbox is running uTorrent.
