I purchased a BMW last week and I'm trying to figure out how the USB system works with an iPOD/iPhone.
I have a 2009 328i with the USB and AUX port in the arm rest. No iDrive system; just the base radio.
When I plug my iphone into the USB using an Apple USB to iphone cable, it doesn't let me control the iphone with the radio or steering wheel controls. I also tried to throw some mp3s on a thumb drive and plug it into the USB port, but it isn't being recognized. It just says "insert" on the radio face when I select USB as the input then after about 10 seconds it times out and goes back to whatever the last input source was (radio, aux).
So, how do I play mp3s through the USB?
How do I get my USB to be able to control my iphone/ipod?
