Seems i can hardly see past my own bumper these days and the 5% tint doesn't help either

Backing up at night is an accident waiting to happen. What are the options for my 06/ No Nav?
I did do a search but I am getting confused as to the nav part, is there a way I can get a visual aid without oem nav?
If so how would the display be mounted?
Thanks to everyone who continually shares their knowledge and experience on these forums.
ps. my husband has the backup display in his rear view mirror, I love that set up but assume it's too much to hope for.
