## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Works great
  

*by K***H on Reviewed in the United States 🇺🇸 on 18 July 2023*

I have no problem with this and it functions properly. I wish they had some type of cable management system when it isn’t being used, but that’s me just being nitpicky.

### ⭐⭐⭐⭐⭐ 







  
  
    Worked on my Honda Odyssey 2012
  

*by J***N on Reviewed in the United States 🇺🇸 on 3 June 2023*

I had some trouble getting the back left panel off to route the cables behind it. It took some tough pulling, start with light pulling in multiple directions until you figure out where the plastic is snapped together. The plug fit perfectly. It has a cover plug that is just to protect the pins when it is not plugged into the vans fuse block. The sticker on the inside of the vans fuse lid shows you rhe fuse #s that match thee instructions I had to get creative with where to place the ground wire. I used several more zip ties than were provided to prevent loose wires and noises. Very pleased, worked on first try.

### ⭐⭐⭐⭐ 







  
  
    Issue with first one
  

*by T***E on Reviewed in the United States 🇺🇸 on 16 July 2023*

Bought this for our Honda odyssey, installed it and it didn't work. But a replacement was shipped quick and worked as expected.
