Help! How to add speedcams to Garmin Map Pilot - Mercedes Benz Original GPS indash

Dear community,
I've tried everything ....
I have the csv + bmp files with the same names with speedcams and used POILOADER to convert it into GPI format. Copied the speedcam.gpi file into Garmin SDCARD \POI folder.
I get the info "speedcam ahead 1000 meters) in a bar on the top of the screen but I can't see the exact place of the speedcam on the road, meaning, the bmp image doesn't appears on the road.

What am I doing wrong? :duobt2:

Thanks for your cooperation.
