Thank you gentlemen.

Here's an update. Rec'd the 13th Gen ULF today and installed it. Everything with the iPhone works!! Tom, thanks for processing that order lightning fast. :D :thumbup: :beerchug:

Great! Thanks for following up. :)

Tom I spoke too soon. When making a call, I noticed my Nav Screen does not switch to the Telephone mode. Interestingly enough, when receiving a call, it does. I thought this might be the ULF's behavior with the iPhone so I tested it with another phone which work fine with the old ULF. Same thing. The switchover worked fine on my 6th Gen ULF but doesn't appear to work on the 13th Gen. Is the ULF deffective?

Right the nav screen does not "switch over" in the newer modules when placing a call anymore. I think it was a little disctracting so they removed that "feature". I like it a lot better with the new features as they made some other great improvements as well.

Of course, it does switch over when the call comes in so that you can see the call coming in and use the screen buttons to answer the incoming calls

Oh OK, thanks for the clarification. I also noticed that on the video that's out there which shows how BT works.

my iphone works fine with the stock ulf that came with my 05 X5.

Are you sure that it is an ULF or it is a TCU (Assist)? :confused:
