Got a Dodge MegaCab with built in GPS display. Has video in back for
passengers, was wondering if anyone knows a way to get video on the
GPS display in front. I know the Garmin street pilot plays video and
wonder if I can get video to work in the Dodge
Though this is not "impossible" to do, it is extremely difficult. There is
no single video in/out wire on either of the units. So finding the correct
wire(s) will be difficult. Once found, running them in easy, however, you
would have to make sure that the wire you are using as an input to the front
unit will allow for what you are doing with out sending the signal backwards
to the nav system.
I can tell you with no hesitation, that when I did this stuff for a living,
we would charge a fortune in labor to do something like this and there was
absolutely no guarantee that we could in fact make it work. I honestly
would not recommend it.
As to state laws, it is not "forbidden" to have the video in front, it is
however illegal in most states to have the video in a position that is
directly viewable to the driver when said video is on. Check your laws
As a follow up to my other post, something that you want to look at BEFORE
you start cutting wires and such. See if the unit up front has an aux or
secondary video input. If it does that is where you want to run the video
from the rear into. On the rear unit will should have 2 or 3 wires that are
your video source, One will be a "ground" and one a "positive" signal, if
you can locate and isolate these, you can use one half of an RCA cable to
run the signal rear to front.
Hope all this helps and answers your question
27602. (a) A person may not drive a motor vehicle if a television
receiver, a video monitor, or a television or video screen, or any other,
similar means of visually displaying a television broadcast or video signal
that produces entertainment or business applications, is operating and is
located in the motor vehicle at any point forward of the back of the
driver's seat, or is operating and visible to the driver while driving the

You are not going to find the wiring diagrams, unless you can get your hands
on a factory manual. This is something that you will have to figure out on
your own, using a digital multi meter. As well as a little cutting and
splicing of wires. Like I said in my original post, this is not something I
would recommend, I would call some of your local car audio shops, see if any
of them have done it, successfully and see if they will provide you the info
(if they documented it.) On average, something like this would take us at
the shop I worked at hours to find the wire combinations before we could go
I wish you the best of luck, but as I don't have your vehicle in front of
me, I can't provide anymore then I have.
I'd thinkit'd be a hard to find item as well. I'm sure an attorney
representing someone would include any person or entity that
supplies such a diagram as a defendant in case that were the
indicated cause of an accident. I understand what you are trying
to do....just might be something no one wants to put their neck
on the block for.
I know for a fact that it can be done as we did this on more occasion then I
cared to when I did this line of work. However, as I have stated, it is not
easy, it is time consuming and there is no way to know for sure if it will
work as desired (or at all) until you do it.
Ok, but read the last part of the last sentence of what you posted, "or is
operating and visible to the driver while driving the
motor vehicle." That is exactly what I have said.
Anyway, as it has already been stated, by you, me and others, the OP does
need to check the laws in his/her state.
The way I read it, several requirements need to be met to be in violation of
1. Person must be driving a motor vehicle, and
2. TV or video monitor (long description above) is operating, and
3a. located at any point forward of the back of the drivers seat, or
3b. is operating and visible to the driver while driving the motor
The portion "or is operation nad visible to the driver while driving"
relates to positioning the video monitor behind the front seat such that the
driver can view it through his rear view mirror. If the monitor is meeting
1, 2 and 3a or is meeting 1, 2 and 3b, you are in violation.
IMHO, if a monitor is permanently mounted between the driver and the front
seat passenger in such a way that it was impossible for the driver to view
the 'entertainment', and the passenger was watching a program, and the
driver was driving during the day (no nighttime glare), the cop would be an
ass (or responding to one) to issue a ticket.
