What is this?

[jeffmc]

This was in my glove box when I bought my car (used). What is it used for? Has the name "Kathrein" on the front and "010.2588" on the back. I thought it was for the sunroof but the owners manual says to use an allen wrench. Is it even part of the car?

Thanks!

From what I understand, it is the tool for the removal of your attenae from your roof.

It's for removing the cell phone antenna on the roof. You may need to remove the antenna if you mount a roof rack. I had the same question when I found that thing...
