Thank you very much for the replies. No i did not try and tell you off because you didn't see something, i just wanted to make sure i understood correctly and everything is clear as it would be very difficult to try and narrow my problem down if i didnt understood you 😁. Anyhow yesterday after your reply i made a copy of my data.zip file and tried extracting it on my computer and thats when i discovered it was acthally corrupted, at that point i tried browsing the web looking for that zip file however i wasnt actually aware what to look for as there are a lot of version of the navigation systems i assume and i didnt wanted to make the issue even bigger. I did not find any download sections in this forum and i did try the search button but came to no avail. Then you said download the build if you need for but i dont know what would be suitable for my device.
Thanks
