Ok.
It very easy for users who knows how to use torrent files.
Go here to download a torrent with iGo8 and maps:
http://thepiratebay.org/torrent/4664108 ... .3.2.64029
When u finished downloading unzip the file to any location u want to (best if u create a folder on your desktop)
Then copy the 2 unzipped files (iGo8 and 2577) on to yours GPS SD card.
When you finish copying insert the SD card into yours AVIC,and do the "Soft Reset" ( a button on the back of your GPS unit). Now it will prompt you if u want to install iGo 8 . Click Yes and that's all.
Questions? Ask. Maybe I will be able to answer.
If somebody still don't know how to do it contact me.
