Headrest Monitor.
 

Can someone with a 2002 or up to 2004 BMW X5 measure the headrest post diameter for me. I need to know what size the posts diameter are and what the center to center dimension is for the posts. Thanks in advance.

i don't have my originals handy to measure, but you can expand the question to include the entire range of E53, and even the X3 (E83) - the headrests' posts are interchangeable as i have verified by my 2002, 2006 E53s and a set of headrests from an X3...
