Thanks for the responses. It seems, well, short sighted on Honda/Acura's part to have it work in this fashion. It would be nice to provide an option to have it function like a headset would, as that seems more universal.
Here's another interesting and useless tidbit. If I bring up the device properties on my BB for the HandsFreeLink it shows three services:
The last one, Object Push, *used* to say OBEX Object Push earlier today (and I find it quite odd that it would change since this morning). Now, I don't have Navi in my TL, and I have not seen any mention of being able to transfer an address book in any of my manuals. I did read about the Navi system being able to accept an address book transfer earlier today, which had me curious.
So I tried transferring my address book, and the BB showed all the progress and declared success at the end. Of course, when I listed the phonebook entries there were no more than when I started.
So, for anyone searching and finding this thread: yes it'll transfer, no it doesn't do you any good
