Just ordered an E90 with the USB interface with the prof. radio.
I know I can connect a USB pen drive to the car but is it also possible to connect a portable hard drive that derives its power from the USB port?
Also what sort of MP3 players will connect other than the Ipod?
I would like to buy an MP3 player, that I can drag and drop MP3's onto, plug it into the USB port on the car to listen over the stereo, then take the MP3 player out of the car to listen to at work.
Has anyone managed to achieve this?
