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.
