My car (2023 Accord Hybrid/ EX-L) has the original auto-dimming rear-view mirror and I am thinking about replacing it with the corresponding Homelink Mirror (08V03-3A0-100). Unfortunately, I can not get a clear answer about whether I need the associated "attachment part" (08V03-30A-100 ) to install this mirror. Honda USA has been no help in resolving this issue saying they have no technical mechanics on staff to answer questions and then refers me to my dealer. My dealer also can't answer the question. I know the part "catalog" indicates that the attachment part is "required" for the Homelink Mirror but my car has a cable installed which already powers the current auto-dimming mirror. I assume the catalog makes this recommendation for those replacing an existing mirror which is not already powered. The attachment part (08V03-30A-100 ) seems to be nothing more than an electrical cable/connector which may be that which is already in my car. Some sources seem to indicate that replacing the mirror is simply a matter of detaching the current mirror and replacing it with the new mirror and attaching the existing power cable. Is there something different about the attachment kit compared to the pre-existing power cable?

Do I need the attachment cable? If so, the expense and trouble involved is not worth replacing the mirror. Any help will be appreciated.

 

I don't think we have many (any) installers here that will know what you want.
You might want to find a group of audio/video guys to ask.

 

Thanks...I appreciate your input.
