Many of us were surprised that Honda did not include a blind spot monitoring system along with the other driver assist functions (some more useful than others). I am thinking of adding one, and would like to ask about any experiences you may have. First of all, please do not comment on reasons why it is not required. I am fully aware of the right-side rear-view camera. I am also well aware of other strategies like properly adjusting mirrors, and / or adding a small convex mirror (even though the diver's mirror already has the small section with a different orientation). I am interested in a high-performance / quality that can equal the performance obtained by factory OEM systems from Honda or other manufacturers. I have seen systems that are optical, or ultrasonic. These tend to be lower cost, and sometimes easier to install but from what I have read, they do not equal the performance of OEM systems both in terms of sensitivity and false alarms. Thus, I would like to focus on microwave (RADAR) systems which seem to be what the OEM manufacturers always utilize. The microwave systems are reasonably expensive, in the $400 to $900 range, just for the components. There is a thread in this forum discussing the Voxx ADVBSD20, where @CharlesBranch persistently tried to get it to work, but failed in the end. I have crossed that one off the list. A couple of others that seem to have good reviews are: 1. The Brandmotion RDBS-1500. Apparently these are sourced by the same line as Toyota. 2. The USASPEC BSM200. Very similar, with a nice adjustable bracket arrangement. Any of these microwave units are completely hidden and install behind the rear bumper cover. Removal of the bumper cover seems to be the most laborious part of the install. Does anyone have an opinion (or better yet, direct experience) with these two (or any other similar units)?
