I bought one of those aftermarket mirrors off of Ebay. It has auto-dim, temperature and compass functions. The problem is, it vibrates pretty bad even on roads that are not that rough. My stock mirror wasn't nearly that bad.

Have any of you had this problem with your aftermarket mirrors? Any suggestions on how to fix it? (besides putting the original mirror back).

 

I used some black electrical tape on the part on the glass, then put the mirror on over it and tightened the small hex bolt. worked for me.
