Hi I'm new and in need of a little help.

I have a 1998 Mercedes C200 which I was driving to work. I had a USB memory stick in my pocket which fell out and down the side of the driver's seat. Although small things that have dropped there in the past have proved to be a pain to retrieve, I have managed it in the end so I wasn't overly concerned.

HOWEVER, the USB memory stick somehow fell into the opening of the hot air duct under the driver's seat. I tried to get it with my fingers but ended up pushing it further in . This minor inconvenience has become a major problem as I have a lot of important files on the memory stick and I'll like it back AND I'm wondering what possible damage the USB stick might causing blocking the hot air passage?

Can someone please help? Can I somehow open up the hot air duct or remove it? Any help would be greatly appreciated, thank you.
