Just purchased a 2012 Honda CRV LX. It has a weird drivers side mirror on it. It has a vertical line on it designating the left end has an angle to it. For seeing in your blind spot I think. I do not like this mirror and want to replace it. We've tried two mirrors so far and neither worked. The 1st was replacement glass for the 2012 CRV. However the back was different then the one we have. My wife ordered a replacement for a 2011 CRV. It looks like it should work, but it just won't go on there.

Our mirror has four tabs that the new mirror will snap into. The 2012 version kind of hooked at the top then snapped in.

Any idea what part I need to swap this out?
