I just made a test and the alert is triggered on all positions shown.
I find the 44x44 icon is preferable because it is full while the other does not display the bottom point . Among other no sound and I found that my
vehicle on the map is not found on a road but more well next to the green at certain times

the file is installed in the garmin poi with the other file
D5388080A.gpi and Netherlands.gpi and PortugalSpain.gpi
