My reply said it needed for moderator...
Anyway i got a workaround, changed the name of my poi to match the same installed, lay it in sd root, and when insert the device asked to copy to internal, said yes and overwrited the poi with all those speedbumpers alerts.
I also copyed the XML to the SD and express recognized it as a 52LM and downloaded the updated 49 states, and copyed it to .system using the update.txt
So now i think i have it all updated and working, will check if i can get the favourites from my dad's device and will be ready.
