Rostra 250-8820 Auto Dimming Mirror Monitor, 4.3 Inch LCD with OnStar

this is CLI song 1 and I just got done installing a rearview mirror as a 4.3 inch screen on it that I'm using for my backup camera and the reason I did this is because back here every rear entertainment system with a 13 inch screen and when this is down I can't see anything out my rear view mirror so my rearview mirror is pretty much worthless when I got the screen down the back and now that I have a 4.3 inch monitor on my rear view mirror I can see just fine when I'm backing up and I also have a lockpick device hooked up on my truck that allows me to turn on the rear view camera anytime I want so anytime anyone's used to the rear entertainment system I can just turn on my backup camera and still be able to use my rear view mirror and in addition have the monitor there's also a temperature gauge for the outside temperature and the inside temperature plus a compass and you can find these
