I guess that BMW won't release a snap-in adapter (cradle) for the 1M suitable to host a Samsung Galaxy S5.
As a matter of fact, even if you remove the existing cradle under the armrest, the size of the smartphone is still too big (you got to put it a bit diagonal, otherwise the armrest cannot be closed). A Samsung Galaxy S5 Mini might fit, though. So if a snap-in adapter will be made available for the Samsung Galaxy S5, it will be for the "mini" version, I assume.
The Samsung Galaxy S5 doesn't fit either inside the "pigeon hole" left of the steering wheel (EURO spec 1M).
Can't speak for other
phablets such as the iPhone 6 Plus, but I guess that it faces the same issue: size matters.
...oh, except if they make a bent cradle.
