Go to bimmerboard.com nav forum and look for my posts #230,716 and 523,380. They have all the P/Ns for BMW Video Modules.

I've been looking in to this too and it is hard to work out, but from what I can establish I think part 65509147139 is a good number.

Roy in GA posted the following list to bimmerboard in 2006:

Video Module (TV module) part numbers are of the form 65 50 x xxx xxx.
These units can be installed in I-bus cars such as e38, e39, e46, x5, x3, z4 but NOT I-drive cars such as e65/66, e63/64, e60/61 and e90/91.
The part numbers start with the most recent I have found at the top of the list and the list is broken into 5 sections. I have seen many of these units on ebay and the remaining ones are from the BMW ETK disks.
Section 1 contains the hybrid analog/digital units.

The P/Ns 65 50 9 147 138/139 were new in 2008 and in my post # 523,380.

Do you know what the difference is between the 138 and the 139 modules?

No, but at a guess one would be a new item, the other a remanufactured (i.e. repaired) item. If not, could just be a software difference.
See realoem for examples.

138 is New and 139 is RMFD.
