Ok, well i'm now struggling with junction view and speedcameras too!
Managhed to find a couple of UK speedcamera files, .gpi format, copied them to an SD card, in the garmin\POI folder.
How the heck do I get them top show on a map? I cannot see them when I look in the location where I know there are cameras.
Same with junction view, I think I have the correct file D2504280A.jcv it's in the garmin\JCV folder, but I have never seen it display.
When I look in system config for the head unit, Base ma, Detail Map and jucntion view are now all displaying correct versions, but I cannot see them on the
screen?
