Great upgrade for my Z4
I ordered and installed both the backup camera and the MMI Prime unit. I took my time during the install and when I had a couple questions was able to get an answer by the next morning via email from tech support. The MMI integrates nicely with the stock system and is very responsive. The wireless Apple CarPlay works so nice and connects immediately when I start the car. This whole system has been a great upgrade to my car.
