Possibly the easiest way of checking, would be to try Pairing someone else's iPhone 5 and comparing results.
If theirs works as it should then it could indicate a problem with your particular iPhone,
or if it behaves exactly the same as yours then it may be a compatability issue.
Unfortunately, according thr Audio Manual that I have, compatability is only confirmed up to iPhone 4s,
but then the Handbook was probably writtten befroe the iPhone 5 was released !,
so it may be worth asking your Triumph Dealer if there is an up to date compatability list.
With regards to the "Poll" - There is a Poll at the very top of your post titled "Connectivity" inviting Members to vote.
There are only two options to select from - "Connect" and "Connect" - do you see that when you view your Topic ?
( If it's there "spuriously" and you can't see howi to remove it,
hit the "Report to Moderator" button and add a Note asking for it to be removed
