It's glued in, I used a small jewelers screwdriver and worked around it scraping away the glue until I could get under it and pry it out. If you go slow, you should be able to do it without breaking it - however, it's pretty much useless the way it's mounted so your call...
Once the compass is out, you have access to the knob retainer screw. Remove the knob and slide the assembly out the mount side.
Thanks you Shellback. I will give it a try---Joe
