hi all i was wondering whether the iPod adapter thing keeps the iPod in charge as well as the obvious task of playing the music, and presumably allow control of changing tracks and suchlike on the steering wheel buttons? I'm considering getting either an iPod Classic or iPod Nano, just as a convenient place to store the my own preferred tunes, and then just leaving the iPod in the car all the time. i presume it does but i thought i might ask as i have never owned or used anything iPod related before
