The one from Garmin, I download the trial version. It shows up in about and setting -> proximity Alerts, but didn't show in map when I am driving. I have clear all the user data and nonvol data, but didn't work. In my 3790, there is a small tip (redlight and safety camera) when I passed by the redlight with safety camera, but it didn't show up in my 3490 converted from 3790. Thanks.
