Review on 🚗 Wireless Carplay Retrofit Kit for 2012-2016 BMW NBT System 3 4 5 6 7 Series X1 X3 X4 X5 X6 - iOS 13 14 Compatible, Android Auto, AirPlay, Mirroring, Rear View, USB Drive, Firmware Upgrade - Road Top by Jamie Behm

A minor flaw but the ability to add a rear camera is worth every penny. And once you start using CarPlay, you won't want to be without it. Amazing product for the money! I have a 2014 (USA) 320i and the only downside is that the audio has to come through the auxiliary input and is not digital. I've never seen an aux that has very good sound quality. If you want to improve the sound quality of your music, you can use the car's USB input, but the hands-free kit doesn't work. To make it easier to switch between the BMW Aux and USB inputs, I programmed them as presets 1 and 2 in the BMW radio.
