So I got an avic s-2 and trying to update it I ended up erasing the maps and maybe even the whole navigation system... So I was wondering if anyone can help me restore the system back to how it used to be? and maybe update it correctly? I need to know things like where to download any files I need, and how to install them into the avic, and yes I dug through this forum already, but couldn't quite figure out on how to make my avic work again..any help would be greatly appreciated!
