[Bama M3]

I did this conversion on my E90 335i a few months ago using the instructions from E90post. You do have to pop off your ashtray cover and reuse it. This isn't that hard, but you must be very, very careful removing the ashtray cover. Overall, it's a pretty easy job.

I plan to remove the sunglass tray from my 335i and reinstall it on my M3 when it arrives. It's actually one of my favorite features in this car.

Good luck!
