For those of you with the older PX3 board and pathetic 1GB RAM on Android 5.1, here is the board upgrade that gave my Eonon GA6166 a much more healthy 4GB RAM and Android 6.0

It is offered by several Ali sellers:

This upgrade saved me from having to pull another dreaded FAKRA cable from under the spare all the way up to the front Nav head area and purchasing a new unit with greater performance.

The 1GB board without a modified ROM from a talented developer at XDA Developers forum was awful. RAM is like HP in these machines, too much is just enough!

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Any of the threads you read are outdated to the point where the iBus adapter may or not have been perfected yet so my question is does the iBus app determine reverse gear now or is the wiring of the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

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. :dunno: :dunno:

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. :thumbup:

Yes, I do see this video interference come and go from time to time with the LED bulbs I have in both the E53 and E46.

I think the solution you seek is a relay that pulls power from a separate source for the camera when the rear lights activate the relay to close it's contacts.

That might be helpful and now I am remembering that this is the way I wired my E53 rear camera but there still appears to be mild interference from the electrical system since without the engine running the video is much clearer.

Possibly a better camera design with greater electrical interference insulation :dunno: :dunno:

Some of the issues come from the BMW lights. LCI has pulse width modulated (PWM) bulb signals and preLCI is analog signals (OV, 12V). I'm sure there is an analog reverse signal on the LCI system somewhere. From the reverse light switch at the gearbox to the PDC module to the trailer module... Somewhere.

The easiest signal for me would be a digital signal of 0 or 1 coming from the IBus for activation. :dunno:

I remember reading something about a tap into the wire that powers the PDC indicator light. IIRC, this pick off can be made in the vicinity of the wiring harness near the battery. A review of camera install posts may reveal the actual description details.

Mike

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.

Yes, I read that last night. I believe that was TerminatorX5 that did that. It think he used it (pin 7) to send a ground to the factory TV module to change the screen on his OEM navigation head unit.
