Ok, first of all, please don't post in other peoples threads with very little information saying things like 'it doesn't work' etc...start your own thread and give the exact details of what device > what map > and the steps you've already taken
So far I understand that that you have an XL Routes device with the latest navcore 9.541 installed on it?
You are trying to update it with United_Kingdom_and_Republic_of_Ireland 1175_13260 map and you're using FastActivate?
You should have extracted that map to the root of your device and it will be contained in it's own folder...the name of that folder should have no spaces in it at all
You should also have FastActivate.exe in the root of your device together with a
fully updated copy of mymeta.txt...download the latter from the following link if you need to:
[Please Register or Login to download file] If those three things are all in place > run FastActivate.exe from the device and select option 2 to activate the map > then option 3 to patch the system > if all is sucessful disconnect it from your PC and test
What is the result?
