Yes, and loosen or remove the dash mounting screws on the side closest to the monitor. Tight fit but works.

Gracerace, So if I replace the camera and the monitor I will get a color back view and the tank levels with the flick of the switch just like the stock black and white screen. I realize the tank level screen will still be black and white. I only want 1monitor....... but just curious how did you split the feeds to 2 monitors???

Yup, all color except tanks.
I took the input from the camera before the Javalina control, hooked it into the monitor 2nd input. The monitors have 2 inputs you can switch with the remote included, or on a button on the front.You'' need to add 12 volt power to it.
One or the other, either the camera or tank levels will be reverse picture. You simply push a button on the front of the monitor to reverse it correct. Then again to reverse back when you switch inputs, super simple.

Just found the pictures. The first is looking down from the top showing the bowed steel retainer. If you look you can see the single bolt holding the color monitor. Shim the bolt to adjust the tension. Total expenditures for camera and monitor $28.50.

Nice install. I need to get un-lazy, and take the old monitor out

I never would have thought about mounting it that way.

On removing the monitor, I can't seem to find a way behind it to remove the cables by just lifting the dash piece up. Did you just unbolt it and pull it out to gain access to the cables?

On mine, I left the old monitor in place. I felt and looked for the cable from the Javalina control box, to the monitor. Just cut the cable, lifted it out, spliced the RCA to the old cable, and plugged it in to the new monitor. Tapped into the monitor switch (selector) on the dash to power the new monitor.Took 10 minutes

I am probably going to pull it out as it will create a lot of extra space under the dash. That B&W monitor is a monster.

Thanks for all the help.

The monitor I bought has reversed image on input one and normal on input two. I also bypassed the javalina for the camera feed. The camera has four tension tabs that just happened to fit the original camera opening even though the camera is round. Works great and the camera even has infrared lights for night use.

Good deal. Post the monitor please. Maybe mine does it too, I just never messed with it.

Well the old monitor is out and the new one is in. Waiting on a BNC male to RCA female adapter. Not a female RCA cord in the house to splice onto that cable.

There seems to be a refresh rate issue, there are faint lines moving up the screen constantly on the tank gauges or volt meter. They may have been there before but the monitor was so bad I would not have noticed.

Taking the monitor out wasn't as big a deal as I wanted to make it. Open the dash, pull up the part with the cup holders. Take out the two cigarette lighter plugs (going to replace with USB ports) and the only nut that was at all hard was drivers side bottom. Was able to move the monitor and mount back a little then it just came out pretty much towards the window behind the door.

I took the radio out at the same time. It was old and ready for an update. I remember 8 track players in cars this one at least had a cassette. There was also a multi CD player installed. I have one in my car and never use it. Most everything is on the phone anymore. I will start looking for an update shortly. Pretty sure when I am done all the old AV stuff will be out except the speakers.
For now they will get a reprieve.

Used a piece of foam core and a bolt to mount the monitor. There is a slot on the back of the monitor, found a bolt head that was a pretty good fit and used a file to make it fit while leaving it snug. I don't have the nuts back on the old monitor mount and it's all nice and tight. I will put the nuts on tomorrow. Basically its a sandwich of monitor, dash, aluminum mount, foam core cut to fit, held together with a bolt fender washer and wing nut.

Anyway, thanks for all the help.

More then likely, when you unplug from Shore power or if the inverter is off, it will go away. Mine does the same faintly.
The adapter is a clean way to do it.
Now you can start on the side camera and 2nd monitor
Good job

If I do more than 1 camera it will probably be 4 and a way to stitch them together. That won't be a $60 fix.

Man, that would be confusing to drive. That is why I choose two monitors. No time to switch back and forth. But still a lot to watch in traffic.
But that would be cool.

I intend to set-up my screen to have 5 inputs:
1. Rear-view/backup
2. Hitch camera for backing up and connecting to trailers
3. Rear-view/backup from Enclosed Trailer
4. Drivers side view
5. Passenger side view

I've been doing some brief research, but haven't purchased or played around with any of the posted options yet.

Here is one option that may fit your needs as you described:

Amazon.com: Pac INTELLIGENT 4 CAM SWTCHR: Electronics

Another option, but likely not without some troubleshooting and finagling to get things working as intended would be a 4-way split screen like this, there are 7" and 9" models:

Amazon.com: E-KYLIN 9" TFT LCD Quad Split Monitor for Auto Truck CCTV...

From one of the reviews, which I've posted below, there are trigger wires for each of the 4 input channels. Similar to what the PAC unit posted above is doing, but all-in-one within the screen. Back-up lights to trigger your rear-view, turn signals to trigger side view cameras, and you could have a toggle switch for the 4th camera.

I just got this monitor today and I thought I would post my initial impressions. For starters, its not a bad little monitor, construction quality is ok, probably on par with most of the consumer stuff coming from the far east these days. Picture image looks to be ok, I have it hooked to a home security camera, so I would say the display does justice to the camera. In other words, its a decent picture, but not even standard TV quality.

I bought this monitor with the intention of using it for an RV where I could have split screen of both sides of the camper as well as the rear view camera on at all times while we roll down the road. It has 4 channels and if you look at the images given, it looks doable. But a couple of problems crop up. The logic for the display modes is screwy. For starters, the display that allows you to have lets say CH1 as the driver side and CH4 as the right and CH3 as the rear which would emulate the views outside relative to looking forward, are not replicated if you go to the split screen vertical mode which puts CH1 on the left and CH 2 on the right. If you go to the triple vertical split screen then its 1-2-3. The instructions are seriously out to lunch, one basic sheet that shows the monitor and nothing much more. There is a menu mode that lets you tweak settings like color, tint and brightness/contrast as well as the ability to reverse the image. Even the seller didn't know about that in a previous answer to a question. There is also an ACC setting that I cant tell what it does, but its a binary step, I.E., it goes 0000, 0001, 0010, 0011, you get the idea. I couldn't tell what it changed if anything and of course there isn't any documentation.

Another issue I hadn't counted on was the level of distortion in some of the split screen modes. The "H" mode is about the worse on the sides. The picture is so stretched vertically that I doubt it would be very usable displaying either side of the camper. Probably the most useful modes are the quad screen or the vertical split for the least distortion. That's probably why they don't show any real images, it would not be pretty.

But all is not lost. Each channel has a trigger wire that will let the monitor automatically switch to that input if it is strobed. So my plan is to leave the display on the rear camera full screen and then tie the trigger lines to the turn signal so that side camera will come on when changing lanes. That will give me a good side view that is not distorted without having to mess with the monitor all the time. I just have to pick out the right cameras that will allow the sensor to be rotated 90 degrees if the base is mounted on the side of the rig.

Think of one picture of your coach from above showing you a lane on either side and 10' front and back. The 360 technology is getting really good at this point.

I understand all of that. I know others will disagree. But I would find this confusing to watch, or look/glance at while driving in heavy traffic. As I mentioned, just having two 7" screen's is confusing enough. But easier then trying to switch back and forth inputs.

I installed the right side camera so I can better watch my blind side in traffic. I don't want it to just come on when I turn on my turn signal. I do this, because in LA, Seattle, or any heavy traffic area, I want to watch my right side, so that in an emergency I can switch lanes safely, at a quick glance. In my humble opinion, this is a case where all those cameras, would be "Too much information" (TMI)

With that said, I like the camera pointed at the hitch. I tow a 22' race car trailer, and have thought about another camera I can switch to, when hooking it up. I do have my rear camera set high, so I can see my towed jeep, but I can also see fairly far behind it.

I do have the capability to reach up, and adjust the camera down, because of the outside mounting. I can easily reach it from the ladder.

The easy thing to do here is utilize a single screen (or dual if you so prefer) with manual switched triggers for the desired view on either. Maybe for you, on one screen you have rear view & left side cameras. You can primarily utilize that for left side viewing during travel because lets be real, are you seriously concerned about your jeep ditching you driving down the road? Highly unlikely given your attention to details. You own a Foretravel. You don't forget to latch you hitch or secure your loads.

The second screen can have 2 switched triggers, one for hitch during trailer connection and one for right side during travel.

This setup would be simple with any of the two options posted above and would allow continuous monitoring of the views that really matter with a rear view at the touch of a quick switch to make sure she's still behind you. You could also utilize this cool looking Chinese push button control center with room for expansion for 2 more functions of your desire (lower fog lights, 50" rooftop LED light bar, etc.).

You'd have to figure out the labeling on your own, which should not be difficult at all with all the digital print folks out there these days.

Nice switcher. Thanks for the lead. I actually do have the lower monitor set to backup, and the other set right side (passenger side). The only switching I do, is push the button on one monitor to see the tank readings. On the other monitor, I can switch to our in-motion satellite. Mind you I don't watch TV going down the road, but in rural area's I can glance at something briefly. I can look up at the TV briefly, but found it dangerous.Normally it's just to see what the song title is. We use it mostly for music.
If you haven't tried watching your multi monitor while driving, especially in traffic, I personally wouldn't get too crazy.The switcher is cool, but unless it was mounted on the steering wheel, it's still going to be tricky switching inputs. The monitors I am using, both have remotes, I threw them in the cabinet. too much hassle.
Love all your good input.
Cheers

I need to correct this, the connector I needed was male BNC to Female RCA. Didn't find one of those but found a male BNC to Male RCA and a Female to Female RCA.

Well finally got around to getting this project done. Replaced the monitor and camera. Not as bad as I thought, the old monitor came out easier than I had thought, bought wire adapters do no wire splicing. The back camera had been replaced so the wire back there had already been spliced I just had to splice and solder a rca plug on it. Everything seems to work good but haven't had it out on the road yet.
