After installing the wireless CarPlay on my BMW 335i, the only thing that was missing was the reverse camera. Fortunately, this was a very easy add on thanks to the add-on I had already installed in the camera. This $35 dollar camera functions as you would expect and has great quality for the price. Install took me about 90 minutes total and it’s definitely worth it to make the car a lot more modern. Hope it helps you install yours as well!
