EasyGuard EBS001 24GHz Blind Spot Detection System with Microwave Sensor - Lane Change Alert & Driving Assistance for Cars (12V DC) | Enhanced Safety for Highway & Night Driving

I purchased this unit with the idea that it would replace the unit that is built into my 30th Anniversary Edition Chrysler T&C (2014 Touring L, I think). I am not sure whether it could be integrated into the vehicle's system because I didn't try to do so. The system works very well as a standalone unit. The seller did not have any idea about integrating it and when asked about it they issued a refund/return option rather than say anything else, other than the old system should be disabled. I have shut it off, but still receive the 'Service Blind Spot System' message and 'Blind Spot System is off', I think, so the system is disabled. I would have liked to connect the wires of the vehicle's Blind Spot System to this system and used the signals to allow the software of the vehicle to run the detection, but there is no easy way to integrate them without more intimate knowledge of the original system and the signal levels of the replacement. What are the chances that they would match up - virtually none. So I went with disabling the old system. Repairing it would have been at least $1000 in replacement parts. And the reason for failure would not have been resolved (the adhesive that held the original sensors to the wall of fender failed allowing the sensor to dangle on the ground until something caught it and ripped the connector apart) because the replacement sensor holders would have to be mounted using adhesive again, assuring the same type of failure in one to two years of use same as the original. The least expensive replacement sensor was $279 on ebay, but $500 or more from the dealer plus installation. How hard would it have been to design mounting plates molded into the plastic for a superior mount rather than to use an adhesive to hold the sensor cradles to the fender material?I declined the return that they offered and went ahead with the installation. As I said, I just went ahead with installation as a replacement as both of the sensors from my old blind spot sensor system were gone, having fallen off the vehicle while it was being driven. I managed to retrieve one of them because it was dangling out the back and someone pointed it out to me. It was beaten pretty badly. The system had been dead for a long time so I wanted to install this system as a replacement.The installation entailed:1. removing the rear bumper2. locating the position and installing the sensors L and right3. removing drivers side taillight to gain access to the wires for both turn signals in my case4. removing the cover where the air pump and tire tools are located and removing the tools and pump along with the bottom protective sheath for the area5. opening the power panel behind the drivers side sliding door6. attaching the fused line to the power line of the 12 vdc socket7. dislodging the interior covers to allow installation of the cables along the door openings8. stringing the alarm light cables to both sides of the vehicle's windshield from under the dash9. attaching the warning lights to the bulkhead next to the windshield with good visibility for the driver10. stringing the cable for the beeper to the underside of the dash11. locating a suitable mounting location for the beeper12. mounting the beeper under the dash13. powering the system and testing operation of the sensors, beeper and warning lights14. reassemble all removed covers to original positions15. re-install the rear bumper16. test drive for functionalityRemoving the bumper was relatively easy - just a couple of bolts and a few connector plugs to dislodge. Then undo the positioning latches on both sides and off it came. Find a YouTube video about your vehicle before attempting the removal if you are unfamiliar with removing the rear bumper of your vehicle. The rear of the T&C has two locations approximately 45 degree flat surfaces below the taillights that were large enough to accommodate the bolt on sensors and space enough to allow them to be adjusted to the 20 degree position that is required. A long level was used in conjunction with the angle tool supplied in the kit to position the sensors relative to the rear of the vehicle after they were mounted. (I also used these tools to determine the feasibility of mounting it there before the holes were drilled and that space was sufficient with the bumper in place.) The kit also provides two screws and a double-sided sticky tape for each sensor - use them all. The tape will not hold the sensor by itself reliably. After checking the area for obstruction behind the 45 degree flat surfaces, I drilled two pilot holes, applied the sticky tape to the mounting bracket and inserted the screws to secure the assembly.The turn signals were available from the taillights. The power for the unit was taken from the 12 vdc accessories socket on the drivers side behind the sliding door. The signal wires for the sensors were brought into the drivers side rear wheel well and the cables for the two side signals and the beeper were fed past the drivers side sliding door along the wiring channel located there to the front at the drivers side where the beeper was located on a flat surface available there - out of sight - and the drivers side warning light cable was snaked up along the inside of the removable decorative covers to the windshield edge and mounted high enough above the dash level to make it visible to the driver. The passenger side cable was brought to the front with the drivers side cable and had enough length to run it along the underside of the dash until it reached the other side, snaked up to the windshield under the removable decorative covers there and the warning light was mounted at approximately the same position as the drivers side had been, utilizing the double-sided sticky tape provided in the kit - again visible to the driver.In operation, I have found that the device functions as expected when another vehicle is in the blind spot area of the vehicle. The beeper is sounded and warning light turns on when the positive speed difference is detected. Unfortunately, the system also detects erroneously on occasion. As the vehicle is driven along a roadway, periodic signals indicate that another vehicle is in the blind spot even though nothing is there. But this is so seldom an occurrence that it is not a problem. The sensor also indicates a warning if the vehicle is backed too close to another object in the blind spot area, but not until you stop and begin to pull away. Kind of an odd warning - too late to help and definitely not expected.All in all, I am very satisfied with the device. I will update this review if anything happens to it in the future. Right now after almost two months of use, it is well within the bounds of reasonable expectations so I am rating it five stars. I did not rate it for 'Sheerness' because I have no idea what that means relative to this device.
