Broken mirror mount
 

Hi all. I am looking for info on replacing my rearview mirror. I see lots of discussion on upgrading a regular mirror to an auto dimming mirror (which I already have) but nothing on replacing a broken one.
The problem is that the ring on the rear of the mirror, where the ball head sits, shattered into several pieces??
So now my mirror is hanging from the wire going into the back.
Are there any replacement parts I can get to fix this? and are there any "upgrade" options (compass, etc) that will fit the mount.

Thanks for the help!
