Most Popular GCH Automotive for 2020 Ram 2500

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.

Image only covers 1/2 the mirror & is too small to see any details

Hard to see in bright sun other than that easy to install

This was fairly easy to install. Works great for lining up on our fifth wheel trailer hitch.

Was easy to install and the quality of the picture was rather surprising. Very clear and bright. Definitely recommend for anyone wanting to ease the hookup for a Fifth Wheel with a goose neck adapter.

The quality of the parts seem good but the directions to install everything were horrible (essentially none existent) and I had to go to [online] to figure out how to remove my factory mirror for the new mirror install and the wiring I figured out by trial and error. The camera kit should have included longer screws to replace the stock screws on the F250 brake light. The order was delayed about a month due to supply chain shortages. Once I got got it all together it works well, just disappointed in the instructions and should have provided replacement screws.

The directions are poor at best. You have to figure it out on your own, which isn't a real big problem, but some additional information would be nice. The bezel for the camera is nice, but doesn't fit 100%. Its close enough, but you have to play with it a little. Additionally, I'm not sure why the camera has a 6' cable, then there is a REQUIRED 24' cable to then connect to another 6' cable to the mirror. I'm wanting to install the mirror in my truck, not the truck in front of me. I don't need 36' of cable, its a Crew Cab, not a buss. So it means you have ALOT of cable to stash. Also, other than changing the brightness, I have no idea what the POWER button on the mirror does. I wired to a switched power source figuring I could just press the power button to turn the monitor on and off. Guess what.. you can't. It is ON. To have this work right, you'd have to figure out a way to wire it to the reverse light switch. And once you find this issue (despite the item description clearly stating the power button can be used to turn it on and off), good luck getting help from etrailer. Was told I would be contacted by someone from technical support days ago... its been crickets. It also sucks the mirror is autodiming, despite what looks like light sensors front and rear, it does not dim (only found that mentioned in the two page "manual/install guide".
