The snap in adapter honestly isn't worth the extra $250 you have to spend to get the adapter for your phone. That's $250 AFTER you have the compatible armrest...It does have that little snap in thingy. (I believe that is the technical term ) supposedly boosts the reception. I don't have an iPhone though so I can't testify for that.
The armrest comes as part of a couple packages or as a stand alone option (at least it did last time I looked at the configurator). In any event, if you get anything with the "enhanced bluetooth", the armrest is the key player.So if you have an iPhone docked in the armrest can it be useful in there or is it just charging? I have my old 5 and was thinking of just loading it up in there to use for music and apps. I am a mostly short trip driver (at least in the MINI) so don't really need to have it charge in there, I can just use the bluetooth for the occasional phone call, right? My current phone is the 6plus so I'm guessing it won't fit in there so why bother.
I've said elsewhere that on longer runs, I like connected. It's nice to have your twitter and newsfeed read aloud to you even though the Facebook functionality is awful. The big thing with Connected is the search function which is weirdly well thought out. It takes into consideration where you are, what road you're on, and where you are going. I used it to look up where the next interstate rest stop was (accurate) and can use it to find businesses and such like in google maps, navigate to them and/or call them. It works surprisingly well. I'm still scratching my head with Journeymate, but I can definitely see the utility in the "find my car" function... especially if you lose your tiny car in a vast parking lot somewhere like Disneyworld haI have MINI Connected on my current R56. I think I've used it 5 times in the past 4 years. Never found a use for it. Maybe it's evolved and is now useful but I never saw the point. As long as I can use my old iPhone 5 in the armrest for playing music then that's about all I need.
