I was optimistic that it would work, after I had read through the reviews. But: It is obvious, and if at all only for classic shaped air vents and not for round-nozzle like in many Porsche Fiat Seat and Mercedes models. The iPhone 6 Plus fits the way purely barely, only by force. The weight of the phone attracts the adjustment of the air vents down so that it does not really sit firmly where it should be. If you have very tight hard adjustable ventilation fan, it may fold, with me they are very smooth and the phone with bracket always goes down and from right to left. That was probably nothing. At least not in the new Mercedes A-Class / GLA / CLA in conjunction with iPhone 6 Plus.
