@Gigya
Yes, thank you for your tag :)
After i read your post couple of time i see on end <Placemark> and see that my kml that work with no problem on iGO primo don't have this tag.
Then i save my kml to iGO kml and have <Placemark> tag inside and after this Nextgen start to show my icone.
Thank you again for pointing me in right direction.
