I have a 07' X5, with IPOD/USB setup in the armrest. I also have the 6 disc changer in the glove compartment.

Issues:

- My 6 disc changer is just flashing constantly and will not accept any disc

- In the i-drive my usb is grayed out

- I can play music thorough my AUX port for IPOD or iPhone

- I cannot charge or get any functionality from my USB

Can anyone shed some light on this, or experience this issue before?
