I just had a lo ok online, There ranges make no sense. 5700,5700 dyna4, 5700s then 6700. they only offer dyna4 on 2 small 5700 global models, not the 6700 global which would be a sensible option surely?
A right bloody load of confusion, designed I suspect, to take you into the clutches of a Salesman so he can work his magic while explaining all the subtleties and foibles of the range...
