Hi guys, question to anyone with the Eonon GA2171s head unit, have you managed to get your reverse camera working?
Mine is all hooked up correctly according to the labels on the head unit but the 12v signal when I put the car into reverse doesn't trigger the head unit to switch over to reverse view mode. I know the camera is working as I can manually start the camera app and select the reverse view option and the image comes up just fine. I've verified that there is 12v getting to the signal wire on the head unit. I've been right through all the settings with no success and Eonon has (not surprisingly) been absolutely no help whatsoever, even after multiple emails.
Has anyone else faced this issue and is there an app or something I can use to manually view which wires there is an input signal on? All I can think is that maybe my device was labelled incorrectly, either that or it simply just doesn't work properly.
Cheers!

Hi
I have KLD unit that I've used for approx 12 months now without any issues (execpt from me playing with MCU and Firmware upgrades). I also have a reverse cam installed that has been working fine since day 1.
However a couple weeks ago the unit started to behave strangely, while I'm driving forward then the canbus suddenly send reverse cam signal to the unit and the unit goes into reverse mode. However I get the exclamation screen, since there is no live feed on the reverse cam (it's not powered on as it is connected to the reverse lights power source).
If I quickly change to neutral (still driving) and back to drive (automatic), the reverse cam screen disappears and unit works as normal. But after random 3-15 minutes it goes back into reverse cam mode, while still driving or even just standing still.
I've taken the unit out and connected it to a PSU and had it powered on for two days at my desk without any problem, so the unit it self seems in good condition. But when back into the car the problems starts again. Today I decided to disconnect it all wiring as well to check everything and look for any issues. I could not find anything "strange" with the wires.
So I started to play around with the reverse cam wires to see if anything was sending a signal while in neutral or drive. Turns out the orange reverse wire from the canbus is powering up randomly when not in reverse, disconnecting the orange wire from the canbus box takes the unit out of the reverse mode and unit works as normal (of course without reverse cam functionality). Same thing happens when I disconnect the canbus box itself completely, then of course my steering wheel buttons does not work (which they do when the canbus is connected).
I also connected the cam to the video IN and engange reverse gear then the live feed from the cam works fine when in ie. the AVIN app.
After doing all this fiddling and testing. I connected everything back correctly. However now the canbus seemed even more "broken", as it now engange reverse entirely when in P, N and D. And disables the reverse cam feed when actually in reverse
This leads me to the conclusion that the canbus some how has gone foobar. However I have no clue to what to look for. Is there a way to reset the canbus box itself, or do I just need to order a new one?
This is what I've done:
- Verify that all settings in Factory settings where correct
- Checked wiring and the car it self (car is BMW E53)
- Checked cam working and the wiring
- Loaded MCU and firwmare just in case
- Tested unit separate from the car (PSU power), working fine
The unit works fine otherwise.
As a workaround for now, I've disconnected the orange wire from the canbus box and connected the reverse cam video to video in. And just manually start AVIN when I need reverse cam
Hope anybody out here has any idea or clues for what I should look for?
Can these canbus suddenly "go nutes" or die?
Thanks

I would rather check the transmitter of the gearbox position. If it has problems it should be recorded as a fault
in your car internal memory. Maybe not in OBD, but deeper. Ask your garage to check the internal memory.

So could it be errors that torque is not able retrieve via ODB?
Thanks I'll check that out.

Most manufactures have at least two layers, maybe more.
I had something similar. Disconnected the pink cable from the reverse feed on the canbus box and hooked it up to the feed behind the glovebox for the reverse lights instead.
Disconnect the battery for a couple of minutes. That will reset the computer and clear canbus.
If it returns, then the PCM is probably at fault.

Hm, tried this. No go:-/
Better get my PCM checked out.
Could it be that my can bus decoder is broken? Anyone experienced this?

Just an update:
I managed to borrow a can bus decoder box from a friend, who has a similar unit as me.
That one worked fine and I had reverse camera as normal again with his can bus decoder.
So as work around untill I get a new can bus decoder box, I bypassed the can bus reverse cam trigger on the can bus decoder.
I made own reverse trigger wire connected from the reverse camera power and wired it to the unit reverse cam trigger wire directly.
Now its all working as before.
I have the same issue. There is another way to work the CANBus decoder (like any update etc), except to bypass the CANBus with cutting reverse cable. Please help me.
I have the same issue as well. I was in the process of installing the rear view camera, after which, my headunit is now stuck in 'reverse mode'. If i disconnect the ca bus decoder box, the headunit starts functioning without any issues. I can't find any info on how to reset or program the can bus decoder to its factory settings. No idea what to do at this point, other than order a new unit.

I think I have the same problem as you. Did you end up fixing it?
If my Canbus is plugged in, it's constantly in reverse mode. The only way to get back to the regular screen is to unplug the canbus or disable reverse mode in factory settings (in which case, reverse camera is disabled)
Do I need a new Canbus? Anyone know how this would happen and how to avoid it happening again?
Problema camara reversa (CanBus)
Hello,
There is, on the market, CAN-BUS INTERFACE UNIVERSAL ADAPTER INTERVAL CAN-01 / 02SPEED PULSE PARK BRAKES ETC
It is marketed by 'Motor Solutions and' Connects2 '
The CAN-Bus interfaces are designed to turn this digital data into analog, so the installation of an aftermarket car radio becomes simple. The interface creates the following for you, and saves you time and money in the process:
Speed pulse signal
Ignition Wire
Lighting wire,
Reverse wire
Park Brakes
I think it applies to 'made in China' radios, but they should consult the sellers
Regards
Mário

not solved?
posted in the wrong place , mtce unit
Hey guys,
I just bought a new unit and have had fun installing/setting it up. But I've run into a few problems/questions that I can not easily solve from searching. I'm hoping for some help. I appreciate any insight that can be provided!
purchased:
MTCB 800x480 (EONON GA2114)
1.) I can't get the reverse camera to work
My previous head unit was the Astroid Parrot Smart and my backkup camera was working. I've setup my MTCB as follows: HU reverse wire to reverse light 12v & HU "cam in" to camera's RCA plug. I'm experiencing: when I put in reverse gear, I get a yellow triangle exclimation point and no proper video. Could this be becuase I have not grounded the HU parking wire (everything else is working properly without having to do that. Is there a setting somewhere I need to change?... pal vs ntsc?
2. ODBD not working correctly.
I can connect to it in bluetooth settings but Torque can not connect to it. I do have blue OBDB icon that appears in the taskbar
3. Keypress (for the physical hardware buttons) volume is too loud
even if I have the radio volume turned all the way down
4. music volume is too loud when volume set at one
With the volume of music at it's lowest setting, it's at a normal listening level.
5. Elements in Settings disappeared
It's just gone. I can't change the physical button colors any more. It was there before.
6. Saved radio stations.
After a scan is complete.... I can't figure out how to reorganize the order of stations.... or even delete the unwanted presets
7. Best way to automate wifi hotspot?
Should I set a tasker action to start hotspot upon bluetooth connect to unit? I sometimes have bluetooth manually turned off though. ... what's everyones solution to this? I though about a NFC sticker placed on my phone dock to automate bluetooth/hotspot.

When you say parking wire I assume you mean park brake wire. The park brake wire has nothing to do with reverse video. It is suppose
to turn off DVD video during driving. Which can be changed in settings BTW. Exclamation point normally means no video. Are you sure
you used the right input and that your camera is providing video? Test your camera on a normal video in and verify if you get a picture.
Also verify that your reverse camera gets 12 volt when selected.
Finally installed a reverse camera on my BMW E46, all cables are right connected and the camera is working during a test on workbench.
My Dasaita V600 head unit (MCU updated to last 2.80 version) dont have a "reverse signale cable" but is supposed to switch in reverse camera through the canbus (E39-E46 software V1.0) so my camera is only connected to "CAM-IN yellow" cable for HU.
Putting reverse gear (motor running or not) the head units dont auto switch to "CAM IN" input for showing images from camera. Anyone had this issue? Any help?
P.S.: If the camera is connected to "AUX Video IN" and manually started AVIN app images are on screen, so no troubles with camera and/or connections.
Thank you in advance

The options was enabled by default on my unit. Tried all options and deep searching for a "software solution" without luck.
Only working thing i find was cutting a wire from canbus box and direct connect the other side from my HU to reverse signal wire from my auto.
I think that was caused from BMW E46 I-BUS signals not fully decoded from canbus, i have retained all steering wheels controls but not doors open warnings, if they are supposed to show on HU display.
If anyone have some advices they are welcome.
P.S.: In my case working for steering wheel controls setting are NO CANBUS. If i try to select another BMW voice from list i lose steering wheel controls.

Can you tell me what wire you cut and connected the blue from reverse light?
BL/GE - Blue/Yellow wire
I understood that it was a wire between the headunit and the canbus decoder.
(on Automatic Gear Box it seems it works just fine)
I know that the data is send and it works The Ibus is able to detect the msg, this decoders just don't catch on older veicules with Manual Gear Box.

Sorry i did not explain correctly.
The BL/GE - Blue/Yellow wire is the one i'm going to connect to a specific wire that is cut from the headunit
What Reverse/Back wire did you cut to get the reverse signal on the HeadUnit+Canbus decoder?

i used the wire number 2 labeled "reverse" on HU side, but you need to be sure that your HU is a Dasaita for BMW E46.
Check the wire/connection label on your HU for confirmation.
P.S.: On kmy case the wire was orange

I don't think it's strictly Dasaita, as this is the same for Eonon as well. I had to tap into the blue wire between the HU & CANBUS converter. I have the power for the camera tapped into the reverse light.
I too have an E46 Touring. I'm curious, where did you mount your camera? I put mine right above the licence plate dead center of the hatch release button. It's a perfect spot! I removed the torx screws and slid it behind the plate light bracket and ran the wires through there as well. It works fantastic in this location and it even assists when connecting a trailer because it's close to the hitch.

installed mine on license plate light.
A question if i can: your HU is capable to show opened doors? Im not able to find that option on my factory settings and also on my unit on Canbus options i have set "No canbus", if i set another bmw choice i lose swc controls.

I've seen cameras that replace one of the lights. I thought about 3D printing an adapter but I went the route I did to keep both lights and have the camera dead center.
Yes, but you need the I-BUS interface to do that. The Canbus converter doesn't do much. With the I-BUS interface & I-BUS app you're able to see what doors and windows are open, what lights are on, and you can code your car as well.
SO I'm sitting her pulling my hair out trying to figure out why I can't get a reverse camera to work. I have a 2013 WRX STi with a Dasaita TDA7850 MAX6. I have everything wired up and working except for the reverse camera. I believe the camera is an aftermarket one from the previous owner. The cables coming from the reverse camera are Yellow RCA, Red power, and black ground. The ground is ..well grounded and the RCA is plugged into the CAM VIN RCA input on the head unit. When I plug the power into a 12v source I can manually view the camera so I know it is receiving power and working.
I have also run a wire from the reverse lights and plugged it into the wire labeled "Reverse" on the head unit(pin number 2). But no matter what happens the head unit won't automatically switch to the feed.
I have also tried doing a 3-way connection between the head unit reverse wire, power wire for the camera, and reverse light wire. This setup turns the camera off when reverse is not on but still won't auto-switch to the reverse camera when the car is put in gear.
I am not against buying a different reverse camera because they're relatively cheap but I feel like the issue I am having is not related to the camera itself but either software or hardware on the head unit not detecting the 12v reverse wiring. I have verified with a multi-meter the reverse light wire provides ~11.8 volts when put in reverse.
Anyone with similar issues previously? Am I just missing a software setting or did I make a dumb mistake in the wiring?
There are settings for the reverse camera also in Factory settings menu.
Check there if reverse signal might be set to disabled.

Thank you SO much for pointing out what I should have already known. This fixed it!! The wording in the factory settings was some really bad double negative english.

Hi,
I have a Seicane PX5 for 2009 Toyota Avensis. I have upgraded to Hal9k 4.10 and upgraded MCU to MTCE_MX2_V3.56. (it came with MTCE_MX2_V2.88).
Everything else works fine but the unit is supposed to switch and display rear camera when it detects that reverse is engaged. However nothing happens.
Camera is connected to "Camera in". Also it does not seem that either of the two wires with "Reverse" on give any voltage when reverse is engaged.
Camera works fine as I tested in aux-video in.
The system is also supposed to switch to "Camera in" when it detects videosignal on there (according to seicanes website).
Anyone have a similar problem or any tips?
Try manually feeding +12v to the reverse trigger wire (orange wire on Dasaita.. not sure about siecane) on the head unit and see what happens.
Thanks for a good idea!
There are two cables labeled "Reverse". One goes into the "AVIn/out" the other comes out of the "ISO-port".
When I trigger the one from AVI with 12v it switches to the camera input.
When I trigger the on on the ISO-port with 12V it also switches to camera input.
So that one must be two reverse-triggers?
The one from the ISO-port I assumed is supposed to go to +12V when reverse is enabled but it does nothing when reverse is enabled (measured with voltmeter).
I do not seem to be getting any voltage from "Cam power" either (which I assume is to go high when reverse is enabled).
I have set this up with the supplied wireless receiver and transmitter and according to the manual from Seicane it should automatically switch over when reverse is enabled or it detects something on the input.
When I run it from the 12 directly and trigger either of the "reverse"-cables it displays the rear image perfectly.
Problem is that I cannot trigger either of the "Reverse"-wires as it is now.
Is it a problem with the MCU-version? I guess I can connect an extra trigger via wire from the reversing lights. but it is extremely hard to get wires into rear hatch (stationwagon ).
Any other ideas?
Solved it by routing +12v from reversing lights to the "reverse"-trigger wires.
