Video plays...sometimes. 4200NEX

Recommended Posts

Hi,

I have recently installed a 4200NEX into my 2013 Ford Fusion. It required purchasing and installing a Metra Turbo Kit that interfaces the car to the HU. My issue is, when I attempt to play a DVD, sometimes I get the video and sometimes I do not, regardless of my parking brake being engaged or the transmission being in or out of "PARK". (I always get audio) What I do get onscreen is the "Startup Warning" with a grayed out "OK" button.

What makes it hard to diagnose any problem is when something works sometimes and not others, when no known changes have been made. I have checked the wiring and nothing seems to be loose or connected incorrectly. All other functions seem to work as they should, including the backup camera. If it were wired incorrectly, it seems it would never work, but that is not the case. It kinda seems like if I do things in a certain order, it works, but not if I do things in a different order. Haven't been able to pinpoint what order though and that's just a guess. Any suggestions to a fix is greatly appreciated.

Thanks in advance.

I just realized what a TR1 is.

 

I tried something similar but it did not work. My understanding is that that type of bypass works by making the head unit think the parking brake is engaged when it is not. My HU does not work whether or not if the parking brake is engaged (When it is not working, but as I stated in my OP, sometimes it does work and sometimes it does not).

Perhaps it's a bad crimp or solder job on that wire. 

 

I use the microbypass and play videos all the time, i use it to change videos for the rear overhead monitor, but it plays up front as well, I just use the mode button to blank out the screen while i'm driving.
