Hi, new here and have a question. I just picked up a 2023 Equinox RS. I searched all over and everywhere it says I should have BSM. But of course the side mirrors do not have the symbol. Does anyone know of a simple way to add BSM? I have searched on Amazon and found replacement mirrors but they are just replacements. I have also found OEM BSM units but require major dismantiling and actually drilling to install a particular type of BSM. Does anyone have a recommendation or encountered this before? TIA
