Just a warning....blocking front field of view, ala the new monitor is illegal in some states. It will give a reason for a stop.
Excellent advice.I know that the original poster's issue was not a blind spot, but it is worth mentioning that the passenger's mirror in post #4 is not set properly. With properly-set exterior mirrors, most vehicles do not have a blind spot.
Although it has been known for decades to set outside mirrors so you see other cars instead of your own (I personally have known about this since before I was old enough to legally drive) this topic was also even discussed once here on this forum: adjusting mirrors for blindspot
With all three mirrors properly adjusted on my C7, the visibility is far better than, for example, a truck with only two exterior mirrors.
Just remember: you don't need to see your car. You can't crash into yourself. You need to see other vehicles. Set your mirrors to enable you to do this.
