I've got the same problem - when I follow these instructions, the ipod UI tells me to follow instructions on the OBC. The OBC tells me to select CD 3, and when I do this, it just says "Accepted", and displays text on the OBC. It seems that I have only got the option to have no text or text on OBC only.

Any ideas? Is firmware out of date on icelink or car possibly (Icelink is new, car is a late 2003 4.6iS)

Thanks.
