You actually dont need to use the 03' bezel, but it would be a little easier. I just got my f700 bt installed and they did use a 03 bezel that i got out of the junk yard for $25. Here is a link of the guy that used his 02 bezel instead of trimming the 03 bezel. This Link helped me out a lot and really got me to decide if I wanted to use my 02 or 03 bezel, Hope it helps
