Similar to Moe's one there - I have a couple of these.

Slightly different form factor (more like a pen that the boxy shape in Moe's link) but works well in the armrest of the F10 where there's an aux in & usb charge point side by said. The first one I got died about 6 months after I got it (could have been due to the kids / wife etc., as they'd be in that car more than me) but at that price I just got another. good connectivity & can be used elsewhere obviously too.. It comes nicely packed with a carry case & a couple of different methods for input. made of aluminium too so has a nice feel & weight to it as opposed to cheap plastic feel of some of the other options out there.
