Does anyone know why US dealers cannot order or install this product sold in Canada on Lexus Models that are compatible? What is different about a Canadian model vs a US model of the same car? Why a harness for this incompatible with a US car? Why US dealers do not even know about the part? (Made Third Party with Lexus or Toyota branding) Why supposedly there is no part no? Since there are no laws in the US against dash cams, this makes no sense. Why a Candian Lexus dealership's parts dept would say on the phone, this will not work on a US car, we had sold them before, to a US buyer and they will not work? Why most Canadain dealerships will not order or sell the part unless you drive from the US to Canada? Why, Corporate Lexus Customer Service knows nothing about the part or the reasons why it is not sold in the US?
