I've bought one of the adaptors to allow normal headphones to be plugged into my XDA Orbit. What I'd like to do is plug a mini USB extension into the XDA then on the other end plug the adaptor in. Ideally it would be 2m long and obviously be male - female. The main reason is that my adaptor lets me charge my XDA up aswell and I don't want lots of cables in front of me. So i'll plug the extension in and run it into my glove compartment, were I'll plug in my fm transmitter and car charger.

Hope this makes sense, i've spent ages googling to try and find one but i've had no luck, any ideas?
