Re: Back up camera?

Thu Aug 24, 2017 4:57 pm

I installed a back-up camera using the padavos method this past weekend. Everything looks pretty good, back-up camera in reverse, radio in all other shifter positions. I have a couple questions for others who have installed a back-up camera using this technique:

1) the fidelity of the image doesn't seem to match what I've seen in other pics on this board. The camera seemed to be pretty sharp when I plugged it into a monitor to test prior to installing, but looks really grainy in the vehicle. Anyone else notice this or have some suggestions to address this?

2) This is the big one - even with the relay installed to set the circuit back to "normal" when the camera is not powered, there is no ability to play audio through the aux input (except in reverse). I did the wife's car first and this has become an issue when she trys to play tunes through her phone or iPod. The aux input functions fine in reverse - it plays even with the back-up video. The bad news is that she doesn't spend nearly as much time in reverse as she does driving! I don't think asking her to go into "stunt mode" and commute in reverse is a viable solution.

Any thoughts other than disconnecting the camera? (I've got her using bluetooth for the phone, but no bluetooth on her old iPod - which is what she uses more frequently)

Thanks!

I connect my Ipods directly to the usb port, using a usb to 30 pin cable. Then in the multimedia menu I have a new option "IPOD".

I followed these instructions: https://sourceforge.net/p/mylink-unlock ... wiki/Home/

Not difficult.

But it's a loser. We lose the energy screens; we lose the onscreen climate settings menu, and we lose some of the climate control indicators at the top of the screen (and those that remain are stuck...i.e., they don't change with the manual control changes...).

Everything else works. Steering control functions. No video-in-motion but that's cause I don't have a rear-view camera, yet.

BringGo USA/Can gets joined by BringGo Russia :D.

And we get MirrorLink. Yay?
Been simultaneously working on the backup camera pavados method while stumbling upon this... Took a gamble after I saw a Spark EV 2014 owner tried the 24.5 firmware with moderate success, only mine's the 2016 model... Do not do it on a 2016 folks. It worked, I have MirrorLink in the app screen now, but not only does that not illuminate when my S7 is connected, Android Auto enabled with the USB cable plugged in, etc, but the MyLink screen in general is extremely sluggish now, responds to touches 2 out of every 10 seconds, steering wheel buttons broken even after the fix applied... AND, the icing on the cake, the MyLink screen doesn't turn off when the 2nd blue wire on the aux connector is cut, effectively making the pavados method worthless on this firmware. I contacted my dealer after failing to find the 16.4 firmware online anywhere (had previously looked before taking the gamble knowing I probably wouldn't be able to downgrade myself) and am going to have to shell out $140 to have them flash the stock firmware for me again. I asked and they will not provide it to me on a flash for those here which I had been hoping for.

Had the dealer roll me back to 16.4, steering wheel buttons and everything now working except the backup camera. When the second blue wire is cut, the radio (MyLink screen specifically..) stays on/responsive. Same with 1st blue and purple wire, don't seem to affect the MyLink.

Suggestions anyone?

Garmin nuvi with the optional backup camera?


It's nice to have a dedicated NAV system in an EV for those times when you are pushing it to the next DCFC.
If the GOM and the Dist to Dest are too close together, I slow down or turn heat down and the numbers separate!
Lifetime map updates, live traffic (in some areas). Take it on vacations for the rental car.

The camera displays quick when tested on the bench. I have not snaked the wires thru the hatch flexi-tube to the back up lights yet , so......

It will probably end up on my Element that the GF drives. She needs it more than me.... :roll:
Used '14 2LT w/ DCFC. +83k miles.
Mostly free charging! Only one LONG visit to the shop....
GM needs Modern Troubleshooting tools for Modern EV's.
3 step Trouble Tree, 1st try car died again, 2nd try not covered / cost $800. 3rd try fixed the problem.

I know I'm a little late to the party, but I wanted to thank everyone on the forum. I just completed installing a camera using the Padavos method. Works great.

I wired my backup camera to the user "padavos" on page 13, (thank you very much) and I noticed that my camera worked without connecting "video-" to the purple wire. I checked the resistance of the purple wire and it is not 0 ohms to ground or "ground" and so I did not connect it. Maybe this has something to do with the audio issue? Also possibly blue wire may not connected to the normally closed contact?

Also using a little lubricant to slip the wires through the boot at the rear hatch worked great for me.

Also, the hardest part of running wires (if you have more than just the reverse camera wire) to the front of the car is removing the side rear airbags. Look them up on ebay (for pictures) and you can see where the loop is that "pops" in place. It takes ALOT of force to pop them up, but once you have it out of the way running the wires is pretty easy. Warning: Disconnect battery for 2-3 minutes before messing with any of the airbags just to be safe.

I also found a camera that is a direct replacement with the correct bulb opening. https://www.ebay.com/itm/332424133532 It is a Special unbranded rear view camera fit for CHEVROLET EPICA/LOVA/AVEO/CAPTIVA/CRUZE/LACETTI/HRV/Spark and has these specifications: Effective Pixels: PAL:728(H) * 582(V) NTSC: 720(H) * 492(V), Lens: 13.5mm, 99mm x 29mm overall dims, screw centers are 77mm center to center and it has a 15mm hole for bulb. You will have to look through a bunch of them on ebay to find the correct one with these dimensions. Also the more lines the better but 700-800 lines is about all video is is good for but don't use a 400 line camera as it will be lower resolution. (The 500+ line looks pretty good.)

Sorry newbie here....but if I use the padavos method...The Video wires have a RCA type input....do I cut the wires at RCA Input connectors to tie them into the First Blue wire with Video + and then other one into purple for Video - ?

Using these Backup Kit wires https://www.ebay.com/itm/332424133532 with the yellow RCA connectors.

If you cut off the plug before the split to the yellow and red connector, there is a shield (bare strands), yellow (video+ connects to the first blue wire) and Red (12v positive) to power the relay to open the second blue wire. 12v positive power is supplied from the back up light at the rear of the vehicle.

Shield is ground for video and 12v negative (car frame ground) are common tied together. The reason you don't need the video ground is because it is already common with the 12v (negative) ground in the camera. Hope this helps.

it takes some effort but you will have a nice back up camera for $20

1.buy an inexpensive $15-20 back up camera and have it power up from the back up lights.
2.guide the video wire together with an additional +12 from the reverse lights to the front.
3.detach the small plastic panel holding the usb and aux female plugs.
4.detach the 6 wire connector on the back of the aux plug
5. the 6wires on the aux connector are in this order blue, blue, black/white, purple, green, grey
6.connect video+ to the first blue wire
7.connect video- to the purple wire (NOT REQUIRED, VIDEO- IS ALREADY CONNECTED TO CAMERA SUPPLY GROUND, JOHNNY )
8.cut the second blue wire.

at this point the camera will come on the screen as long as there is video feed and in our case the car is in reverse,
however the radio and everything else will be dead because of the cut second blue wire.
to make the radio work again the cut blue wire must be connected back together,
to do that we will use a standard 12 volt automotive relay

9. use a 12 volt relay like an automotive one with 5 pins,
10. connect the +12 lead you just brought from the rear from the reverse light to the coil of the relay or contact no 85 on a standard automotive relay.
11. connect the other side of the relay (contact 86) to the common of the relay switch (no 30) and also to the cut blue wire that is still attached to the wire connector (that will be 3 wires together)
12 connect relay switch contact no 87a which is normally closed to the cut blue wire coming from inside the vehicle harness.

that is it, when you go in reverse the relay will energize and open the 30 to 87a which a normally closed switch
the radio will go off while in reverse
when you shifty back to forward the relay will de-energize and let the switch close again, effectively connecting the 2 blue wires back again
and the radio will come back, it tool me a whole day to figure it out, but you can do it an an hour or two. enjoy

ps i dont see way to add a diagram here, email me if you want it bbnnvvb@yahoo.com

Hello everyone, I know this is an old thread but I can confirm this work fine with a Spark EV 2016.


Thanks Mr. E.Poi for your all you efforts in doing this write-up!
