Will ask again...the mystery can be solved if you decode your VIN...do you have option code
S3AGA Reversing Camera listed? Based on the pic...no...but what if the camera was removed due to some other occurrence we don't know about...like a trunk lid replacement?
It doesn't appear on the USA side of the part database...but if you look on the Euro side...there is a retrofit rear camera "kit". You select the part number based on how your car is optioned...then the kit will come with the parts you need for a successful install.
If you do go this route...you can order from the Euro side of the part database from any BMW dealership. If you look up the number first, you'll need to let the counter person in the parts department know that you got then number from the Euro side of the database.
