Had a little convexed mirror sitting around, and have seen a few mounted on the heater vent by some guys, but mine was a little big, so I made up a bracket, and with a little velcro, this is where it sits,,
Cheap, works, and easily removable,,,
Here's a few pics

I should mention I cleaned the area of the dash with alchohol for a better stick,,,

NIce field of view, even with the door on,,,,,,,that Taurus is right beside me 10ft away





Little notch to get it sitting closer to the tweeter



Sticky on one side velcro

 

Not bad!!! I'm gonna do this. I didn't want one on my vent either and I like that you can take advantage of the larger mirror. Already saved your pics for my next low budget mod!!! great job and thanks for sharing!!!
