Excellent indeed!
I just joined and posted on the (old) thread "reaching back a route after leaving it" (p17499).

As I mentioned there, I navigate on the basis of track-trips because that's the most accurate (you get what you see, and vice versa).
I create my routes in MRA routeplanner and export as tracks.
My Zumo 350 (or Basecamp) converts a track into a track-trip (tracks created myself on MRA and those received from another club member).
A track-trip does not indicate planned stops (coffee, lunch, gas,...), at least not on my Zumo 350.
I recently found out that I can use custom POIs for that!

Did some tests: works fine.
Just a detail: the magenta background of an icon displays, while it is supposed to be transparent (not to be displayed).
I read an older post of yours where you had this same "problem".
May be it is due to the image format? Apparently, you no longer have that problem anymore.

Thanks for all the useful information.

Hmm - I don't seem to have taken a note of that. I've got the yellow dot though.

It was a BMP image file 36x36 and had only 16 colours with magenta being set as 255,0,255 (RGB) I have other icons that are larger or smaller. But all BMP. All 16 colours. Maybe that was the limitiation. I can't remember and I don't have a note of it (that I can find).

Thanks for the icon jfheath. I downloaded it and will give it a try this weekend, testing detours too. (I am organizing tours for our club this year and want no GPS hick-ups along the road.)

The post where you mentioned that magenta is not transparent (as I experienced):

"Magenta is supposed to be transparent, but it isn't. I made a 9 square icon with areas of all 8 combinations of Red Green Blue. eg 000000 Ff00FF. None were treated as transparent."

In fact, that's how I found this forum, and your posts, by Googling "garmin custom POI magenta transparent" or something like that.

I indeed suppose it's a question of color format.
I saved my icons using MS Paint in the .bmp 24 bits format, reasoning 24 bits is 3 x 8 bits, 8 bits defining a range 0-255 for each color.
But I realise that wasn't the right choice, should probably be .bmp 256 colors or 16 colors as your icon.
