Okay I had copied the metadata file into the incorrect folder in that case, I added it to the 'FILE' folder where all the other files resided, I now have added it inside 'com.tomtom.ukireland'. I also previously had 2 extra folders called 'android' and 'data' which i have now deleted and renamed. I still just try it before doing the wrong method which came up with the same 'unable to connect' message, so will now just go back to the car and try again. Somehow I think i'm still going to get the same error message but you got to try!

No it didn't work, same message again.
