Hello everyone,
Been reading for many years this great forum. Now I've decided to make a post, as I could not find any relevant thread about my issue.
I have a VW Tiguan, with factory parking sensors installed and some weeks ago I installed an Android head unit. It is a Chinese brand called Eunavi with Android 9.
The unit is quite good for the money (it is called Eunavi 2 din 9'' Android 8.1 9.0 TDA7851 Car Radio Stereo for AliExpress), but I come up to the following issue:
Before installation of the unit, I had the LCD car stereo that came with the car by VW. When I was putting the reverse gear, the LCD screen would come on and display the parking sensors for front and back. This specific screen would stay ON, until either the parking brake would be turned on (meaning: the car is parked) or the speed of the car would be over say 10km/hour (meaning: the car is unparked and going).
The new android headunit now, does not work like this. When the reverse gear is on, the parking sensor screen is also turned on. But all the other conditions are not considered, so when you are simply trying to park or unpark, you are only able to see the sensors screen only when in reverse gear and not if you are going forth.
My car has this parking system also working with the push of button that is enabled with the reverse gear and goes off the way I mentioned.
Do you know if I would be able to connect the cable for the reverse gear from the unit to that specific button?
Or, even better, Is there any other way to programmatically add the specific conditions to that parking sensors screen of the unit?
Kind regards,
Panagiotis
Hi, Could you please tell me did you ever managed to fix this issue and how? I have a same problem.
Me too, but with aftermarket parking sensors. I can't connect them to android unit display. Reverse camera works fine.

Hello everyone.
People, I recently bought a car radio of Joying brand. The model is the JY-UQ130U with RK3188 1.6 GHz processor, 7-inch screen, 1024x600 resolution.
Anyway, I'm having a problem with this car radio. Every time I turn off my car for a longer time, for example thirty minutes or more, the radio information is reset (time, date and presets radio stations).
Is there anything that can be done in this case? Is there any way to prevent this from happening?
Taking the opportunity, it is possible (and recommended) to make the car radio works with the car turned off and without putting the key in the ACC position I?
Thank you very much.
I hope you can help me.
You have it wired wrong. One of the cables require 12V when the cars switch is off. The other 12V power wire wired to be off when the switch is off. The clock requires constant power. Probably reversed the 2 12V wire.
Not a radio problem.
Joying 10.1 with 6.1 update
96 lexus ls400 with 6.0.1 marshmallow started having serious issues. First, the display won't turn off. It continues running even if the car is off with no key in ignition and the car is locked. Also the buttons and screen light up but the buttons don't work at all, not even the power button on the detatchable face or the reset button next to it. Also, the USB connections don't work so I can install my photos videos or music via usb...what the heck is going on? I haven't had the unit for a year yet and I take excellent care of all my belongings especially my cars. The manufacturer takes a year and a day to respond and hardly speak clear even in messages so I'm lost. No warranty either. I've tried everything except returning it or buying a new one or taking it apart.
Due to the problem of Opel Astra H having the 2-Din slot quite low, I want to try to install a head unit in the place of the standard Opel display on top of the dash panel. Since there is not enough space behind that display, I'd have to install only the display of the head unit and then put the unit somewhere else - maybe behind the actual 2-Din slot or the glove compartment. Since I don't have a head unit yet (partly because it depends on whether I can do the above), I thought I'd ask here.
1. Looking at pictures of various HUs, it seems removing the front panel with display should be no problem, for example on this unit - https://de.aliexpress.com/store/pro...ith-Octa-Core-2GB-Ram/600991_32805474302.html . Is this the case or are there HUs with the display glued to the HU or otherwise unable to be removed?
2. Is there just one flat cable connecting the display to the HU or are there more? I'm talking about HUs with touch buttons, like the Dasaita unit linked above, not ones with rotary knobs for Vol/Tuner and mechanical buttons for Home, Nav, Radio, etc. Maybe someone can upload a picture of his HU with the front removed?
Hi All,
I just got this unit from amazon. I have the quad core 2GB RAM 16GB ROM 10.1" version which came with Android 8.1. Installation was easy and the unit seems very nice and fast enough but when ever I try to open an app like spotify or youtube or even OBD apps the screen goes black with "DO NOT operate while driving" error. I tried installing a third party launcher and it caused this error every time I tried to go to the home screen. Google maps does not cause this issue.
I currently wired the rear cable to ground just in case wiring causing the issue but that did not help. Under the settings there is no option in the video section which would allow me to turn off this error. Overall the rom on this as is looks half baked missing bunch of options. I do not even have a system update option for me to flash a different firmware.
Any suggestions that could help me get rid of this annoying issue and use this unit properly?
Thank you all.
Seems nobody cares but I finally figured out the solution. Under settings>car options>about there is another settings button. If you select that and enter "8888" it will take you to the deep settings menu where in drive options you change "Break" to "0". This will get rid of this bug permanently.
Thanks in anyways.
I care
I just had the same exact problem with the same radio
thanks so much for taking the time to update your post!
Do you have anymore information on tips and tricks for this radio?
Hi, tried this on my mekede head unit, took a few minutes to figure out which menu to follow and the part to alter but it worked great. Awesome. Cheers

Good job on figuring it out... I went through this with the same exact head unit...
Let me expand on this "problem" a little further please...
So most head units now are more than just a radio/CD player ..specifically ones with DVD players (or ones that can play any video really) the manufacturers can be held liable for people getting into an accident while driving because they were watching a movie or had a movie playing (Cant fix stupid) on their head unit located on the dash (as well as it being illegal in most (if not all) states in the USA).
REAR DVD players are exempt from this because... well they are in the rear... and not in the driver's line of sight.
With that being said, one wire on the harness that came with this unit (wire #23 I think) is labeled " BRAKE CONTROL" - IF (a big IF here) EONON set this up like most other head unit manufacturers that make an in dash DVD/video display, this wire needs to be connected to the brake switch so that it receives a signal saying that the brake is "on" and the vehicle is not moving...therefore "SAFE" to operate this unit (watch a movie, video, make setting changes, brew you a cup of coffee, paint your nails etc etc etc......)
Because there is NO REALLY good diagram for wiring this to the brake switch... you are left with a guess as to how it is to be done. (Should just be a positive connection from parking brake to wire.... I think... I guess...)???
This brake safety feature has been in other units for years and a LOT of people negate this circuit (I wont list the ways... it's easy to figure out) I even know of some car installers that worked for a national electronic retail store that would "bypass" this circuit in the customer's cars.
I am glad Eonon put this programming control into the back end of the unit because I, (having installed a few radios in numerous vehicles I have owned) REALLY didnt want to go through the trouble of bypassing the circuit... so shutting it off, on The unit was just as well for me. 1 less wire to worry about.
Just go into the root menu as stated above, and select "BRAKE" then adjust to 0. This removes all enable/disable requirements for that circuit.
Great unit so far... wish Eonon would spend more time writing a more informative instruction manual.. and maybe hire an American or British to actually write the darn thing so people could understand it.
Hope this helps.
I have the same unit but I can't get the panel to light up. Anyone knows how to wire to the car to get the panel to light up?

Panel as in the buttons not on the touch screen? (Ie power, volume up volume down )
Wire (I believe its orange or blue in color if my memory serves me well) regardless it has a tag on it that says "ILL" or ILLUM... that's for illumination. You need to figure out what wire in your car is for illumination for the stereo... if you cant, run a wire from your headlight switch that controls the parking light. USUALLY, there is a wire for the stereo to make it light up when the headlights are turned on. You just need to find it.

Yep. In the Eonon harness, it's an Orange wire with a tag on it that says "ILL". just hook it to any wire that feeds your dash lights.
Dears,
anybody tried Eonon GA2178 - 10" Android 9 Head Unit?
I'm actually on Eonon GA2168K - 10" Android 8 Head Unit, it's a good device with minor problems.
Anytime developers fix a problem they introduce an other problem and there's no community support for MTK chipsets.
Because of this I'm evaluating the new Eonon GA2178, that is quite similar but based on Rockchip chipset.
Tks!
Brake setting
On my Ga2172 the brake setting shows open close or speed, so which is it to watch video on the move?
I just chatted with Eonon and they told me that none of their units show the backup camera while it's booting... That's a blow considering all of my vehicles have android headunits and this seems to be the only brand that doesn't have this as an option. I don't have my MCU and ROM info handy but, has there been any discussion about ways to show a backup camera during boot on units that don't have it working out of the box? Unfortunately there are no other sellers who have the "flat face" head unit for my Range Rover, so I'm at the mercy of the unit I have installed.
Thanks.
EDIT: It's an Eonon GA8201A if that makes a difference.
What's wrong with it showing the reverse camera upon reverse? While booting seems odd, especially when the OS is having to load.
Nothing else works while its booting so i wouldnt expect the camera to be any different, what model range rover do you have ?
I just fitted an Eonon GA2175 to my D3/LR3 but yet to route the camera cabling.

I has nothing to do with the OS loading and so on. It is normally activated by the reverse gear. Than it gets an electrical signal and the camera video is simply going over everything else. No OS interference at all.
So it could display on start if you have the gear in reverse.
If you do not have the gear in reverse it will not show. I don't know any unit that does this when not in reverse: OS loaded or not. Because it is not controlled by the OS, but by the electrical signal when in reverse.
This is from a central electrical signal: If it would function it would also mean that upon starting, whith the car not in reverse, also the reverse backlights would be on. That would be confusing and thereby dangerous.
Does your webcam work while the PC booting ? , no because the os still has to load before any peripherals will work which is no different to the head unit regardless if you select reverse or not.
My head unit displays the reversing signal through the OS. The Android firmware automatically switches depending on the reverse line. The only way I could see this working the way you say is by using the output of the head unit to the display + the reverse camera and then using a relay to switch between them. Completely separating the OS from the camera feed.
Its wrong design from eonon if this is the case.
The rear signal in all other px5 or a3 or a8 units is controlled by the mcu so when you switch the key and you put reverse no matter what the addon android card does it switches to rear camera.
I dont believe they had done that and you must wait the android to boot ...
Hi,
I have a joying head unit (uis7862 6GB+128GB 10'1 " 1920x1200) The unit is mounted in a VW tiguan and uses the harness with canbox.
I do not have nor do I intend to have a reversing camera.
The problem is that there is no way to disable the reverse camera mode. When I put car in reverse, the black screen and a small graphic with the car and parking sensors is displayed. When I drive forward, the front parking sensors trigger a large car graphic with the parking sensors indicators on it.
I would like to disable the rear view camera but keep the parking sensors functional when reversing.
In the car settings there is a "cancel the reverse into the front view" option which looks promising. - however, this option does not work, and its setting resets to off every time the device goes to sleep.
Joying recommended cutting the orange cable between the canbox and the unit. This indeed causes the reversing camera mode to not display. However, the parking sensor graphic does not display either.
The problem is that the rear parking sensors are not triggering the car graphics to appear. The sensors do work, however, as can be seen in the graphic, when both the front and rear sensors are triggered at the same time.
Does anyone know how to solve this problem. Ideally, the rear sensors should trigger the same graphics as the front ones.
Marek.
