I use a GPS and Wayfinder with my N800 quite a bit and really like it. However the sound, though much, much better on the N800 than any other hand-held, is not as loud as I'd like it.

Currently I'm plugging the N800 into my car stereo and that works very well, except I can't listen to the car's radio.

I'd like to get a set of mini-speakers, somewhat like the Nokia MD-4. Problem is that the Nokia MD-4 runs off 4 AAA batteries.

Does anyone know of similar car mini-speakers that can run off the car's 12V cigarette plug rather than off batteries; or perhaps has a mini-USB plug as the power input for the speakers?
