techies please!! mp3 car connection and charger?

hello, i have a 1996 firebird formula with stock stereo. i have an mp3 player (non-ipod). I would like to connect my player without having wires or a cradle showing, and control the music from my factory stereo. ideally, the mp3 player would be in the glove box. also, could it charge my mp3 player? is this possible? can you reccomend a product for me??

thanks!!
