problem with routes in garmin xt on miopocket

hi there,
i recently unlocked my mio moov s505 using miopocket 4 (installed on SD). so far so good!
After that i managed to install garmin mobile xt for Windows Mobile v5.00.20wp and seems to work fine.
The problem is that i can't load a route created in basecamp to my device.
I create the route, i am sending it to the storage card (i connect the sd using a card reader), it goes to a folder into garmin->GPX but the garmin xt can't load it!

any ideas??
thanks!
