Hi all. I spoke with Mark from the company Prestogious Society. The company manufactures override units for a variety of car brands. He said the override for HondaLink is built, which would allow HDMI while driving. He says he needs cars to test the unit on before it goes to production. It is "plug and play" so no harm to your car. Does anyone live near La Habra, CA and want to assist? Mark's phone number is (562) 644-3268. The website is www.prestigioussociety.com
