I paired my iphone and went to the phonebook (on the nav computer) and mine said "please wait"

I waited for about 10 minutes (because I have a lot in my phonebook) and hey presto... it worked...

Another thing that I have learned is that the caller id (when someone phones you) won't show on your screen because the iphone does not support rmsa (remote sim access)...

Hope this helps..
