I am planning on getting a new car, and FIAT carmaker is including a multimedia
system called "Blue & Me" which also adds bluetooth handsfree phone
capability, and voice commands.

Blue & Me — or Without Me?
The minor problem: it runs Microsoft Windows Automotive or
something like that, and even worse: it adds a Windows logo on your
steering wheel (I mean, with all honesty, car is bound to be full of
proprietary software, so I can either choose not to drive any [which
is an option I would be close to taking, as soon as public transport
in Belgrade improves]). I mean, I can live with Microsoft's proprietary
software as much as with any other, but I can't live with having
a Windows logo in my face. :)
Still, it should be possible to replace the Blue & Me software with
something else, but I wonder if anyone has tried that, or at least
knows what hardware is it actually using?
What I would actually be interested in is the USB port, which is
again only provided with the Blue & Me option.
