Avin Avant 4. Number of us on here have installed them. I think they look the most "factory". I've had people comment after riding with me after the swap they didn't realize it was different until the back up camera came on. It comes with a canbus adapter so things on the wheel work. You'll also want the IBUS adapter so you have access on screen to all of the data you would have with an original NAV unit. If you have DSP stereo you will also need the IBUS adapter for that to work as well. This one: https://avinusa.com/avant-4-multimed...mw-x5-e53.html

Get the P6. More memory is better/faster. If you have factory NAV you will need the extended quad lock connector cable to run to the rear.

This head unit is some of the best money I've spent on my ride. Gets used every time I drive it. The things it offers are so far and away better than the factory stuff that it's almost like driving a newer car.

Don't waste your money on the GPS. Just download Waze and tether your phone to the unit for wifi. The real time traffic data makes it much more useful.
