@Titanic Thank you very much, i made it.
From this post i have been able to download 65_66 loader.. So for someone who was struggle with the same issue. Just downloaded it, copy/paste it in the Clean SD Card. Just started the GPS and automatically started loader and updated firmware. After that i just installed the maps with MapsetToolkit for Basecamp usage and than used Basecamp for the installation into the GPS Memory Card.
