They appear when you are on a route and then after.
Set up a simulation route, start driving it, they show up.
Cancel the route and they still appear on screen until you do a Hard Reset or you connect to PC.

Touch the dot and I get an info bar identifying the poi as the required rest area.

I just don't know what 'normal' behaviour is for 34xx.

Perhaps someone could kindly upload a 'working' custom icon they have and I will use poi loader to combine with one of my gpx files to test.

Yes, in Browse Map, when you try to search them using the transparent bar on the right, they appear as blue dots, like all other original Garmin pois.
I beleive that this is made by Garmin, because you don't anymore search "a point on map" but "an area" (blue circle) and if there are many big icons in the circle, is not easy to show all of them in such a small place.
Go back to the Navigation Map and they appear with their custom icons again.

3490 can show both 8 bit AND/OR 24 bit icons (yes!) at the same time (8 bit and 24 bit .bmp in the same folder)
So we can use our old 37xx icons and any new 24 bit we find/draw.

3490 can also show transparent icons, using Magenta color (R:255, G:0, B:255) as transparent color, but only if the icon's color is 8 bit.
[Only registered and activated users can see links. ] I have most of the custom icons I use.
