What year LX do you have? Did you buy the DVD bypass module from e-bay? Where did you tap into to get a video out signal?
No ,I did not buy a "module". The "module" is an empty black box. Somewhere on this thread , you will find the instructions on "How to by-pass' the ground for the emergency brake. Also, in the same information , you will find instructions on which wire is the 'video"output wire. I haven't "tested" the new lead . I'm still trying to find a flip-down screen. By the way , it is a 2002, LX470.
Good luck, it works great. And the instructions are right on the money.
