Exactly correct...and also the reason for my question. As stated above, I am reluctant to tie myself into purchasing a product specific to ipod/iphone integration as it does seriously limit my options. I have however discovered a few other options which are better at achieving the result I am after, namely the use of USB which then provides me with the option of connecting a hard drive. As a bonus I still get to use the iDrive and steering mounted controls to navigate the hard drive as if the CDC were still connected (which is all I'm looking for).
