What do you guys think about this Android HU?

I don't know how this happened but it is not supposed to come with the extension harness but they sent it to me anyway. No complaints here.



Bench test video.

Have you installed it yet?

I have started the reading, researching and planning stage of my install next month. One of the most common features people add is the reverse camera and I want to know more about the wiring and activation of the cameras. If you do a few searches for E53 backup cam you will come up with plethora of old posts dating back to 2006 for the addition of backup cams to OEM navigation systems with the TV tuner.

And then the ones that have posted videos of installs of cameras on the android systems are just plain hacks. Wires running everywhere, not securing of wiring, wires not properly routed, etc. It is just painful to watch.

Any of the threads you read are outdated to the point where the iBus adapter may or not have been perfected yet so my question is does the iBus app determine reverse gear now or is the wiring of the camera trigger to the reverse lights still necessary?

I want to learn more about the latest android systems and how the installers provide the connections for the reverse cameras and/or dash cameras.

To my knowledge with the iBus app 2.1.0.1 that I have attached to my Android 6.0 Eonon GA6166, there is no knowledge of the reverse camera by the iBus app. The camera display in my HU is triggered by a signal from the reverse lights (presumably positive voltage) that triggers the HU to display the rear camera input.

Thank you Mike. I see a lot of that same wiring logic and protocols on the web. But surely there is a reverse message in the Ibus, the PDC feature knows when it's on...

One of the problems the X5 has is many have tried to wire the power of the camera to the reverse lights and has caused video quality interference, momentary operation and hot check bulb warnings on the dash. Since I will be going with the DVR recording my cameras will need to be powered to be on with radio or ignition position 1/2 source.

I notice that the AVIN allows you to set the cameras to continue recording even after leaving the vehicle for up to 2 hours so I am try to contact them regarding the wiring of their cameras for that feature to work. One would think the cameras would be wired to HAAT and honestly sounds like a potential battery parasitic drain issue.

There has to be a proper way to wire these cameras, I just am struggling with the different systems, different features and different algorithms.

*EDIT* I see you over on E46F too. Never realized that was you.

The Seicane has an ibus interface box for the steering wheel controls and such. This has to be whats triggering the reverse lights since I cant find any factory harness wire that is for the trans being shifted to reverse. Since the radio goes into backup camera mode with no extra wiring done by me and the factory harness plug not having a dedicated "reverse" signal wire it has to be decoding it from the bus with the provided box. If the car was here I could test this by unplugging the ibus box that came with the radio but the wife is at work right now.

Found a little more info from autopumpkin.com. Here is a basic layout of one camera harness like I think I have ordered. It also shows power from the reverse light 12V but on our BMW's this causes issues. So with a relay it should work but still, this only has camera powered up when reverse is engaged. I want the camera powered up always when key is on for recording purposes, not for viewing on monitor.



Another wiring schematic for some different camera systems that have a dedicated analog reverse light signal sent to the HU if you don't have the help of IBus messages to indicate the reverse signal.



And finally, the message at the bottom:

BE NOTED:
If your headunit is using the CAN BUS decoder box to control the reverse signal, then the reverse detective wire should be already connect between the CAN BUS box and the headunit, then you no need to care about this wire, just connect the RCA jacket to the camera input port from the radio.

Nope. Probably won't be fora bit either unfortunately. I'll start an install thread when I do though.

Ob, it was necessary to use a relay triggered by the pdc trigger at the back of the truck. As mentioned, on an lci truck using just the tail lights to trigger a reverse camera will result in the camera not functioning properly due to the pwm.

My avant 2 install details this. It was a complete pain in the @$$ to install. Especially with the camera that used to be provided by Avin. To do it properly, and not make it a hack job takes considerable effort. Which is why so many installs you see [I]are[I] hack jobs. Here, the insanity starts at step 28.

Wow, CW. Unbelievable write-up, how did I miss that? I guess my searches have always been for Avant-3. The amount of detail you put in is truly amazing. I read the entire post from start to finish.

So on the custom circuit board for the reverse cam I am assuming you didn't have the Resler IBus interface at that time so you needed a different path to trigger the reverse event. I like the added feature of the PDC button command but I am not sure it is needed for me with the newer evolution of android HU I can simply bring up the rear view through the app within the HU. Still a nice feature you with TerminatorX and Smokey53 figured out. Kudos.

I design, build and install data and video acquisition harnesses for the motorsport environment and it was nice to see someone with the same OCD for fit and finish as I have. It makes all the difference in the world when you stand back and look at your efforts and results. When I look at this picture, all I can say is one word. Professional.

Thanks for sharing.

Here's another one, with some physical buttons looking more OEM:

Look what I found on AliExpress

But it's for e46, wondering if it fits our dash?!

They do not interchange.

Besides, that's another quad core. Stay away.
