Hi; I have a 2014 SV CrewCab with a factory installed backup camera. It only comes on when the gear shifter is on reverse but I would like to change it so that I can view the backup camera whenever I want to. For instance, when I'm driving I can view what I am towing to check load security.
Is there anyone who can advise me on how this can be accomplished?
Definitely interested as well. I thought about this several months ago since I have a small trailer that I sometimes tow. I can't see the trailer when backing up unless its on the screen. So when I pull forward to realign I am blind as to what angle the trailer has changed to.
http://www.nicoclub.com/FSM/Frontier/2014 Frontier/av.pdf page 217. Looks like you would need to put a switch in the wire that it in position 50 on the wiring harness that would let it go to ground which should make it think that the truck is in reverse. I have never tried to figure this stuff out before, but it is what I get from the FSM.
This method looks promising but I'm hoping that this mod won't also activate the reverse lights as I am driving around. It wouldn't be a big deal if it's a just a boat launching operation, but may attract highway patrol attention if the reverse lights come on while driving.
Been wanting to do this as well. Hopefully someone tries it and figures it out. Had an aftermarket deck in my Xterra with a backup camera that could be turned on whenever and it was very handy.
You have to supply 12v to pin 50 and it will work. I did add a backup camera to my 2014 sv factory radio which did not have the backup camera (no vtp).
sounds like I had it backwards, but was looking in the right spot. Mine is a 4 banger S model so I do not have a camera to test with or I would for you guys.
I have a bypass button installed for just this purpose, however I'm not running the OEM setup. Yet, I should be able to help.
My Kenwood head unit uses a sens wire that switches on the backup screen image when it receives 12V+ on that wire. That sense wire is tapped off of one of the reverse light wiring harnesses in the back of the truck.
For the bypass, what I did was wired up a momentary switch (small, pushbutton, under the center stack). I also installed a 1-watt diode on the sense wire coming from the reverse lamp. For those who aren't sure what this does, the diode allows current flow in only one direction (from the reverse lamp to the head unit). This is the key to ensure that you won't be sending voltage back to the reverse lamps when you hit your bypass button.
I imagine you can do the same with the OEM setup. However, you may need to tap into the reverse sense wire and install the diode there (so it won't send 12V back to the ECU, or wherever that signal comes from).

Hi all, this is one of the main reasons I joined the forum, I was hoping to do exactly what the OP proposes for the exact same reasons. I have a '14 king cab with a 6 spd manual and no nav, when I put the truck in reverse it comes on. I'd like to be able to turn it on/off with the press of a button and check trailer loads, etc. I'd also like it to never make that godawful noise, ever. The noise on/off button should be perfect since it's already there, and it's already wired in the system. I'll do some homework and see what I can come up with.
One solution (many variations are possible) - 2013 factory wire colors are shown:
Locate the Blue wire (pin 50) at rear of receiver.
Cut the Blue wire and splice in a diode and a wire for the switch.
Tap into the ACC line (Green/Black at rear of receiver, or elsewhere) for +12V.
Mount and wire the "camera on bypass" switch.
Done.
Is there anywhere else to locate the blue wire which goes to pin 50,don't want to pull radio out of dash.I' getting old and lazy. Any one else tried this yet?
You can see the backup camera by going in the diagnostic menu:
Turn off the radio, hit preset number one and turn volume button clockwise for 30 clicks, Go in diagnostic and camera system. You now see the backup camera

does this work (diagnostic menu) even with the '14 SV -no reverse camera? Does the # of clicks need to be -precisely- 30 or does just 'a bunch' suffice?
The SV with no reverse camera is the same as with the reverse camera if you were unsure.
I did this in a different car (Prius) some time ago. I need to do this in my Frontier, but have been waiting for warmer weather.
Basically whatever is used to trigger the backup camera on the display. According to an earlier post, +12v switches the radio display to camera. As long as you put a diode in the circuit to isolate the backup lights, you should be fine.
One question is whether the camera (in the back) also is powered when put in reverse, or is on whenever the ignition is on. May take a little extra work to power up the camera.
I also want to install a selector switch to choose a different video source. Such as a front camera (maybe night vision) or an ipod video jack mounted in the console next to the audio connector.
I will try to pull the FSM schematics and figure out what needs to happen to make this all work.
Obviously a switch would be better, but I love the diagnostics trick thanks @Mathieu424 !
I drove the whole way home from work with it on. Only downside is the menu artifacts on the screen, but still I can see me using this when I have a load in the back that covers the back window.
According to the 2016 manual, AV with NAV, with or without amplifier, pin 28 of the AV Head Unit is reversing signal hot, from pin 2 of the backup lamp switch (M/T) or off the backup lamp relay which is controlled by the TCM (A/T), & the wire should be sky blue.
If you are going to feed this hot, I would place an in-line diode near the AV connector, in the harness, then add a switch supplying 12v through another diode, to the AV SIDE of the diode, otherwise you will power up your backup lamps and whatever else that circuit feeds.
