Hey guys,

I have the X920BT bypassed and I have a BOYO backup camera attached to this unit. A week ago I found a video on youtube showing that I can have the backup camera on while driving. I think I also saw a thread here too, but can't seem to recall the title.

I just went to my local installer to ask about this and he told me that he would have to change the wiring around so that I can control the camera manually. However, he said if I do this, I will lose the ability of having the camera auto turn on when I put the car in reverse.

What can the installer do to allow the automatic ability, but also add in a manual ability of turning on the camera? He mentioned that because the unit is bypassed, he would have to take out the bypass for me to get the camera to work this way.

Thanks!

Your installer is completely full of crap and you should fire him and go somewhere else. If he told you this he doesn't know what he is doing. Don't have him work on your car again. You can do what you want and it is very simple. Its even in the damn install instructions for both the unit and the camera. Any installer worth his weight will know how to do this.

this can be done with a simple SPDT switch.

lol yeah, that installer doesn't know what they're doing.

A switch is not even necessary.

Yeah, in settings just change view mode to rear view.

I know how to turn it on (i have it on my shortcuts), but it's "BLACK" right now because the power is only on when I am in reverse.

What is a good switch I can use? Thanks!

@VBlue - Would you happen to know what page in the manual? I read most of it and don't recall it saying how I can connect the backup camera a different way, so that I can have the camera turn on whenever. Thanks

I just don't want to lose the automatic ability of the camera.

In the install manual. Also there should be info in the install manual for the camera. Once again there is no switch necessary.

I just checked both the X920BT manual (online manual) and the BOYO VTL-425 camera manual. THe camer manual has only the installation pictures and nothing else. The X920BT manual doesn't tell me how I can connect the camera.

The only thing I see in the X920 manual is something about the "POLARITY", which I can change, but I do not believe that is what I will need to do. What page are you talking about VBLUE?

The INSTALL manual, not the owners manual.

Wire the camera to ACC power. Make sure the reverse wire is connected to the AVIC. Done.

The INSTALL manual, not the owners manual.

The backup camera only has ONE manual which includes everything. Is there a X920 install manual online? I can't seem to find my manual for that.

Thanks Jason. I didn't look at the camera before the installation, but I'll ask the installer about this. Thanks so much!

We just went through this at my shop and here is what you have to do. The reason you are getting a black screen when you manually turn on the backup cam screen or switch it in the view mode is whoever installed the rear view camera has wired it for power from the backup lights therefore it has no power unless you are in reverse. Change the cameras power source to a acc power that way the camera has power whenever the key is on and therfore will work anytime you manually switch or change the view mode. Jason had it right, I just added some details! Hope this helps make it more clear for you......

Thanks, that reply is very helpful. The installer said it can be done, but he just said i'll lose the "automatic" ability when I go into reverse. This means I will have to turn on the camera manually every single time. The installer said he did this before on his older unit and changed it back because he wanted the automatic ability when the gear is set into reverse.

He also said because I have this bypassed, I would have to lose the bypass mode or something. He may be wrong or may not be. I just want to make sure. Thanks you guys.

At the risk of sounding redundant, you should look for another installer b/c you do not need a switch nor should you have to give up the bypass to accomplish what you're trying to do. I have the same setup as you, installed everything myself and have no issues with the camera. Here's what you need to do:

Camera Power: Connect this to switched power, this way the camera is always on when the car is on; now when you switch your nav view to "rear" you will get the camera feed.

Avic Reverse Input: Connect this to the car's reverse signal wire. All this does is tell the Avic that you're in reverse and switches the input to the rear cam.....hence no manual switch needed.

Video Cable: this should be obvious.

None of these connections have anything to do with the bypass, so I'm not sure why your installer thinks you have to give up the bypass.....again, you're best bet is to get another installer.

Hope this helps.

You dont lose anything and bypass still works fine. Worked fine on cars we did. As long as you still have reverse wire hooked up to reverse lights then the automatic backup cam will still work, you just have to keep your deck on Pos+ trig for back up cam and make sure you are swithching 12v through your manual switch. The only problem you will have at this point is your backup lights will come on when you turn on switch. Here is how you can fix that! You will need to use a relay and put 12V IGN to post 86 & 87. Connect 85 to one side of your manual switch and the other end of the switch to ground. Take your wire comeing from your backup lights that is going to your reverse trigger wire and cut it, then connect the side going to the backup lights to 87a and connect the side going to the deck to 30. Now when you switch your manual switch (with backup cam wired to IGN) the deck will see the 12V propting the backup cam screen but backup lights see nothing. When switch is off everything works normal. This can also be done by installing a one way power diode in the line to the backup lights beyond the point that you have tapped in with your switch but relay is my preferance. A reputable shop should know how to do stuff like this and I am always bothered by people that say "it cant be done" or "wont work". I believe if you dont know then just say so! Your installer may be a good one if he does good work and doesn't mess up your car so not saying he's no good but maybe he still is learning and should rething the way he answers questions he is unsure or uneducated about. LOL. If you need any more clarification let me know.

Other member is right, you do not need a switch but we have installed the switch in several applications because it is faster, easier, and more convienient than going in and changing your view mode. Example, we have done several systems for a local tow truck company and they like and prefer the quick and easy method of just flipping the switch. Especially when you need it in a hurry. So I feel it is more convienient to do it this way but other member is correct, it is Not neccassary....
