No problems. Go to the following website:
http://www.pocketgpsworld.com/uksafetycameras.php
Near the top of the page, it will tell you to 'click here to download the latest database'. Once you have downloaded the database on to your computer, you need to unzip the files. You do this by double clicking on the downloaded zip file and then selecting the option to extract all files.
Once they are unzipped, there should be a folder which is named speed zoned. Click into this, then there should be two folders. One is Gatso's and the other is Mobile. Click on the Gatso and copy the .ov2 files and the coresponding .bmp files onto the storage card of your tomtom go (put them in the same folder as the map).
Then do the same for the mobile ones.
Now that this is done, disconnect your tomtom go, turn it on and ensure that you activate the speed camera warnings in the points of interest section.
Let me know how you get on.
