Hey guys, as the title states I just picked up a silver 528 last week. I'm coming over from 2 VW and an audi, so I have a thing for german autos. Anyway my car came with the business tape player and no CD changer so for now I'm rolling ghetto tape adapter to a portable cd player. My friend just picked up an Audio Link for his RX8 which basically connects to his factory CD changer outs and has a USB out which he connected to a small hard drive. I looked around but couldn't find an audio link for the E39. So my question is there a similar device for our cars that will let me connect a small hard drive to use as an MP3 player through the cd changer outs in the trunk. And if anyone has an indash Cd player that they want to trade for a tape deck +$$$ let me know. Thanks!!!
