I'm not sure the business radio supports USB thumb drives, I've only used this feature with iDrive. iPod input with this radio requires Y-Cable (analog audio input).
Make sure you order BMW Assist to get Enhanced Bluetooth.
I ordered the M Sport package myself. I didn't get it in our 328i or 128i and regretted it specifically for the steering wheel.
