I have added the speed camera database to the XF car sat nav system and set an audible alert for each camera type. This works quite well, although it doesn't audibly warn you until you are almost at the camera site, but it does at least show the different camera types on the map. I got the database via Pocket GPS World. The only mod I had to make was to split the mobile camera file into two as there are now over 9000 mobile camera sites in the UK and a file with this many POIs was too big for the system. There are different files for each camera type, each of which shows with a different (supplied) icon. Admittedly this does not help with your thermic windscreen issue but it does provide an alternative for those with the built-in sat nav. Chris
