Rear-View Mirror Vibrating.

[IsLNdbOi]

I'm having a problem with my rear-view mirror vibrating too much when driving and even sometimes when idling at a stop. Sometimes, all I see in the mirror are blurs because it vibrates too much.

It's not the original mirror that came with the Yaris. Shortly after purchasing the car, I replaced the stock mirror with a CIPA 36500 mirror with temp. and compass. I hadn't had this problem until recently when I installed this:

It's a mounting base for anything you'd want to mount (cell phone holder, radar detector, GPS, etc.). To install it, you remove the rear-view mirror from the wedge on the windshield, then slide this mounting base onto the wedge. After it's slid onto the wedge, there's a screw you have to tighten to secure it in place (just like the rear-view mirror). Once the mounting base is in place, you slide the rear-view mirror onto the wedge built into the mounting base then tighten the rear-view mirror .

I did all that and the mounting base is solid and doesn't budge at all. However, the rear-view mirror vibrates alot even though it is tightened down very tightly onto the mounting base.

I've Googled a little bit and found others that have the same or similar issues with their rear-view mirrors, but I haven't found a solution yet. I tried putting some 3M double-sided foam tape between the rear-view mirror's mounting "foot" and the mounting base's wedge (that the rear-view mirror's "foot" slides onto), but that didn't help either.

Anyone have any ideas on how I can stop this vibration?
