Hi,
My car came with one, I thought it was really cool when I bought it. The writing on it says BMW, and I saw a few a while ago on sale on ebay.de (for like 10 euros), they're actually made by Siemens. anyway, here is a crappy photo of mine, sorry I don't know how to use a camera properly:

Edit: speakin of which, anyone actually has a working phone analog car phone? I've been all around and spoke with lots of phone company reps and all the answers came back negative.
