Most Popular Third Brake Light Camera System for 2021 Ram ProMaster 2500

I love it it is the best Backup camera

This product doesn't work. The app won't show an image. The menu doesn't work. I've tried uninstalling and reinstalling and registering. Still doesn't work. This product is garbage.

I would have given this a higher score if it were not for the lack of decent instructions or how the mirror actually works, Secondly, I don't like the fuse placement on the mirror, I will splice it out and add it somewhere else that is accessible. I do like the fact you can connect 3 cameras, again, no instructions how the mirror switches between the two. After testing, when a camera is powered, the screen show that particular camera. I will be adding the cargo cam and an additional front cam to my aux switches so I have control over them. Also, the cargo cam is 620 lines, as advertised but no specs on the mirror monitor. After receiving the item, the mirror only produces 480 lines. Not deal breaker as the picture quality is good for a 4.3" screen. Haven't installed yet, but did bench test on the cargo cam as well as an additional cam I purchased. Works flawlessly. Overall, not a bad product, just need some more info/instructions and options for the mirror fuse.
