I just got a DMH-W4660NEX put into my 2007 Toyota Highlander Hybrid. Working fine so far, it I get a pop up saying that the speed sensor is not connected. It goes away quickly and doesn’t affect my ability to listen to audio. I’m not sure what that really means. The shop did install a bypass, but not sure if that affects this message. I just don’t like these messages popping up on my screen.
firmware is up to date.
