I’m just about to take delivery of a 2016rt le. It’s got a Sat Nav mount for the bmw system satnav. I was scrolling trough here and see a garmin zumo 660 fits to the mount without connecting to the scroll wheel thing. Is there a bracket available that would allow some way of getting my iPhone 7+ there instead. The phone is waterproof and I’ve used it on my gsa with no problems. Thanks. JJH
