i left my tomtom on the table, and my little one, has taken my sd out of the tomtom, en threw it by the garbage

Now i have a tomtom with the stupid screen that the sd is missing.
replacing the sd is not a issue, but finding my ttgo.bif does.
it was on my sd, and i cant find in on the internal device.
have you guys an idea?
Thankyou lads.
