Hi, this is my first contribution to this forum and also my first post.
This will allow you to run the latest IGO Amigo version 8.4 on most Sony Nav-U devices. I have mine working perfectly on my U53 as shown below.
Remember to always backup your original device software incase anything goes wrong.
All you need to do is download the 2 files below, they contain 2 folders that you need to copy to the devices mounted volume. Backup and delete everything from your mounted volume and then copy the 2 folders over.
It's pretty simple, the first time it loads it will ask you if you want to load IGO Amigo, say yes and it should load, it will take a while the first time.
All you need to do then is get the maps and 3d buildings etc into the relevent folders. This will work with 8.3 and 8.4 maps. Its the same folder structure as IGO8. But you will have to create your own folders
