Touch & Go usb port

[denial]

I own a toyota yaris 2012 with touch and go and i am trying to update it through usb port or play mp3's but the sticks dont recognized by navi.

I tried 4 different usb sticks (4gb/8gb/16gb) as fat16/fat32 even ntfs that does not supported just to be sure.

If i plug in my iphone charges normaly so the usb port has power.
When i plug the usb stick the light of the stick flashes for a while but noghing happens :/

Any suggestions before i go crazy please :)

Thank you !!!!
