Considering the rear window contains the antenna elements for both the remote key as well as FM, I'm not sure how you can point straight to the amplifier if someone was having both key distance and FM reception issues...

The last resort is to try a new amplifier. If that works, then it was the amplifier problem. Otherwise, it was the rear window problem. Make sense ?

Thanks for the guide! I used it when I replaced my diversity antenna today.
Here are some tips and reference pictures to help the replacement go more smoothly:
1) Fold down the split seat and remove the head rest. Then sit on top of it facing forward like a passenger and lean backwards so that you can get your head under the back window to see the clips.
2) There is a roof liner clip and should be pulled down to gain more access to the amplifier.
3) Grip the back edge of the amplifier, and push against the front clips to release it easier.
4) When re-installing, get back clips in first, then press up from the bottom to get the front clips to lock in.
5) The most bottom C pillar clip didn't want to clip in for me. Frustrated, I elbowed it gently and it clipped in

In total, this will be the second time that my diversity amplifier has been changed. 1st time was under warranty, and 2nd time is today.
The part numbers:
Factory install diversity amplifier: 65 20 6 931 719
Revision 1 diversity amplifier part no: 65 20 6 988 057
Revision 2 diversity amplifier part no: 69 20 9 193 836
BMW must have known that the diversity amplifier was defective... why else would they revise the diversity amplifier twice

GREAT POST!!! Only took me 10 minutes to replace mine with these instructions. It really helped to know which way to push and pull on things. Seems to have made a BIG improvement with my FM reception.
THANKS!
THANKS!

Been a busy day today, managed to get the brake fluid done and also installed the latest revision of the diversity amplifier to resolve the progressively worse key reception distance.
Thanks for the guide, it took less then 10 minutes, knowing which way to push the amplifier and clips definitely helped
