## Description

desertcart.com: BlueDex Universal Blind Spot Monitoring Assistant DC12V Car Lane Changing Warning 24Ghz Millimeter Wave Sensor Detection System : Automotive

Review: Works great! - I will admit, I was hesitant because the reviews are mixed but I decided to take a chance. I then kinda dreaded the install because I figured it would be difficult. It was not too difficult. I fished the cable that goes to the front of the vehicle with a wire and then pulled the cable through with minimal interior plastic removal. The ground had a terminal already attached to ground to the chassis. The power had a fuse insert I was able to plug into a vacant spot in my fuse block that had power when I turned the key on. Soldered and heat shrinked the left turn signal wire, right turn signal wire and reverse wire at the rear. I decided to tape the sensors on the inside of the rear bumper cover. I cleaned the inside of the bumper with brake cleaner and used 3M automotive double faced tape. I have used this before on car door moldings and it is very strong so I think this will hold well. I placed the warning lights right at the pillars and they are bright enough. Took a test drive and it worked perfectly. I could see the passing vehicle coming in my side mirror, just before it went into my blind spot the light came on and then stayed on until I could see it to my with my peripheral vision. The passenger side worked just the same. I am very pleased with this purchase and the performance of this system.
Review: Good but needs mod for my car - Works well, however in 2018 malibu brake and blinker share the same wire, resulting in beeps when passed at stop light. Going to use a nc relay controlled by the brake to disable the buzzer when the brake is pushed.

## Questions & Answers

**Q: Does it work with metal bumpers?**
A: No,it can't. The detection radars are installed on the inside of the rear bumper of the car and cannot penetrate the metal. (The detector signal emitting surface cannot be blocked by metal).

**Q: Is any drilling required ?**
A: No need to drill holes. The detectors take the inside of the rear bumper sticky mounting design, and you need to confirm the angle when installing it.

### ⭐ Waaay to complicated to install.

My mechanic, who installs engines and rebuilds transmissions, wouldn't touch it. Quick refund, though.
