Finally managed to download 28 files and unrar them.
When I open the iso img in the Tables folder and then 0 folder it appears as follows:

0079.ASC
0079.IDX
0080.URL
0080.URL.URL

Is this correct ?

Also how can I change the icons to the Uk style english cameras for both the splash screen and the icons that appear on the map ?
Where can these be downloaded and added to the iso img ?

Thanks
