I have the same problem with my F40. I downloaded the French Aires POI's with originally could not be recognised as the supplied *.csv (excel) file.
I convert this file to *.csv (MS_DOS) file format, it was then recognised by SmartST but when loaded gave the same results as yourself.
I'm still trying, might get back to you.
As I said, I have come back.
If you are having a problem with your Navman not accepting the POI file, go to POI_EDIT (gdt software).
Create new POI file or import your new POI file.
Once imported Save the file (to wherever) as a (Navman) CSV file.
Once you have done this, go through the importing sequence with your SmartST software.
I did this and got all the POI's imported as well as the Icon's, and it works
