These are interesting part numbers and I'm a bit confused.

- The 3G adapter 84-21-2-151-038 I assume is the latest iPhone 3G adapter, and I suppose the 84-10-9-182-792 is the older regular iPhone adapter, is that right? Do you by any chance have a list of all the iPhone adapters that could be made to fit the E53?

- Do you know if the iPhone 3G adapter 84-21-2-151-043 will work in the E53?

- Your console eject box 84-21-6-933-415 comes up as a Euro spec only part for after 1/2003 (prior to that it was 84-21-6-924-067). Any reason why you specify that one and not the one specified for the USA which is 84-21-6-946-063 ?

- The bumper antenna you specified 84-51-0-016-669 which I understand is the entire retrofit kit and retails for $213.95. A number of people have indicated that for the USA all that is needed is the one I mentioned that is 84-11-1-470-326 which retails for $63.75. What do you think?

Here are the BMW parts on the BMW USA website. I'm curious as to your thoughts about the differences.
