We can't offer individual builds for every country in the world, so you will have to download the application and the maps separately, but it's just a case of copying the maps and other content into the correct folders.
To make it easy for you, Go back to post #1, Read it, scroll down to
iGO 8 for Binatone devices. and download it, use Fichier hosting as that was working when i checked it 30 minutes ago.
Here are the UK maps

This is a guide to the content files

You won't need all the files as some are Primo only.
Using the information linked to above you can build up your UK version yourself, and copy it to your device (sd card)
If you did it correctly you will see iGO start instead of the original app, If you see an error message like
Application database cannot be found. then you did do everything correctly, but we need to tweak a file...
