Android Radio Buzz in RV - Android Head-Units

I got a generic px6 Android unit from AliExpress for my RV. It works great when the RV is running off battery power.
As soon as I plug the RV in and it is working off the 120 to 12 volt converter, there is an actual buzzing that comes from the chassis of the radio (not the speakers).
My first thought is to try a capacitor to help correct the "dirty power" but curious if anyone else has a thought.

...not android auto.

Suggest your "converter" checked, that noise is very bad powersupply/ buck converter noise, that is being suppressed by chokes inside the unit.

Crap... not android auto. Android radio... mods?

[Q] Charging Circuit Location

Hi, is the battery charging controlled from the A500 or the plug-in power supply?
I am hoping I can just put the correct plug on a spare 12v 1.5A supply
ex-egll
Don't know your answer directly, but if you find a thread somewhere in here about the power button led colors, there is a link someone posted to the A500's repair manual... Maybe something in there can help you.

Interesting document..... Thanks
and I just found the A500 Diagnostics Tool.zip the guide references It's on some Russian site, and not sure if I am allowed to share the link, just search google for it and it is easy to find.

Just Bought. Erisin ES3015V 8" VW Android 5.1 Car DVD GPS Player

Hello All,
as the subject says I have just recieved my "Erisin ES3015V 8" VW Android 5.1 Car DVD GPS Player" just for information, if any one wants to know anything about it just ask, id be glad to share.
http://www.erisinwholesale.com/spec...v-8-vw-android-51-car-dvd-gps-player-466.html
First impressions, looks good, feels ok, every thing ive tested so far worked great, bluetooth, wifi connected to hotspot on phone, radio (great reception) navigation.
Its super fast and responsive, must go into sleep mode because its instant on when you push the button.
If you want any logs or screen shots, dumps etc you might have to tell me how to get them, as its my first android head unit so im still playing with all the settings etc.
Also trying to find a goods apps or things you can do with it as I love to tinker.
Kind Regards Guy
Hallo also bought the Erisin 3015GE and is instantly on after pressing the button. Hope it will not run the battery flat.
So far confident with the device.
Need to find out how the 3g connectivity works, there is no options in settings.
Just went out to see my batteries flat, need to figure this out.
I had the ACC dip switch on the back on when it should have been off, now the stanby and complete shut down work a treat.
Regards
Hi, I've also just bought one of these units but I'm thinking the display is questionable as the colours seem very washed out. Any chance you could take a photo of your unit on the home screen to compare?

Did you try 3g connectivity ?
I cannot find any options for it in settings
Thanks

My unit arrived with all 4 DIP switched on the off position, and so far I haven't had a flat battery and the unit powers off when the key is removed.
Can you guys give us a quick review of the unit, I am trying to see if I should buy this or another.
Also, is this bright enough to see in the daytime? Color accuracy?
I had some issues with the colours on the unit I received, and was offered to be sent a replacement main board to replace myself, or to return the unit for a replacement or refund. I opted for the refund and ended up getting a similar model from Joying.
The support were relatively helpful, although you had to wait a day for a reply due to the time differences between here and China. (I imagine that is the case for all the similarly priced manufacturers though)
From the limited use I gave the unit it seemed ok, the weather app on the main screen wouldn't update, I believe there is a firmware update available for it but Erisin don't seem to make the firmware publicly available. As I was returning it anyway I didn't look particularly far into this, so there is every possibility Erisin have a patch for it.

Hallo checksum
The brihtness of display is ok, The brightness settings are not possible to be dimmed enough for night use.
There is an icon to dimm the display completely which i use.
Need to figure out if i can link the display off function to some button.
Ale colours seems to be fine. Not tried any dvds, need to drive when I am in the car.
But can somebody share experience with FM reception ?
My reception is more poor (in central europe)
Connected to the oem antenna, and only strong signal stations are received well. Lower signals are terrible and i have falouts of stations and crossing of 2 signals. Or the station runs good and in few 100m comes to serious disturbtion of signal.
Oem radio was having absolutely perfect reception.
Anyone have other experience with fm ?
Does anyone knows how to connect the 3G dongle. Wanted to stream music from internet instead

I just order this one. Is it still good? Thx
got mine since yesterday. very fast boot times under 20 seconds. quick response. iGo preinstalled on 8gb sd card. i dont found a volume changer for subwoofer pre-out. the forgot this definitly.
display is too bright in night-mode. you can only lower it a little bit. the good thing is that you can turn it completely off. maybe the thread starter found out how to map this to a hardware button?
good fm quality.
whats the code for changing the boot logo? is it 126?
Hey ho,
Code is 3368.

You need to enter factory settings in settings menu. Then it asks you for the code

I figured out how to power off the screen with a hardware button.
Enter factory settings with code 3368. Choose the buttons menu on top.
Choose the first option (not touch buttons)
Press the hardware key which u want to use.
I choosed the power button. Now you can choose for short press the screen off symbol and long press as power off.
Save it and you're done
I really like this headunit now ?

Does someone has experience with the DAB+ module for this unit? Is the radio reception better as for the FM radio?

How about the external Mic jack - if an external mic is connected, is the internal mic disabled or is it still working? Does this unit also require the BT hardware modification for the external mic to work properly?

I'm sure this varies, but I bought this unit a week or so ago, with MCU 1.63.1 and Kernel 3.0.101+. FM reception isn't great, but not horrible either. Have only driven in the city though. DAB+ reception is fine, although I don't really like the app and the antenna that came with the package is useless to me (looks like an antenna made for your desk, not a car). I'm in the process of finding a window antenna instead. Once I get that sorted and hopefully find a better dab app I'll be happy.

Shield Remote very sluggish, slow to respond

My Shield TV remote is often very slow to respond. Sliding/tapping the touch area or any button just doesn't respond and I have to press buttons several times or wait 10 seconds or so to get it to 'wake up'. Once it wakes up it seems fine for a little while (20 minutes or so) but then the problem returns. It seems like the remote is disconnecting and needs to reconnect before I can do anything with it. If that's the case, is there anyway to disable this behaviour?
Does anyone else have this problem or know what the solution is?
Yes, I've got the exact same issue.

Tried swapping the HDMI cable. No improvement for me
I've done some more testing and it seems to be specific to the Shield Remote. If I use the Android TV Remote app on my phone, it's very fast and responsive. This leads me to think it's a problem with the remote itself rather than software on the Shield.
I read some threads elsewhere that interference from other devices can cause problems. I've removed both the other devices that were near the Shield (a Google Home Mini and a PS4) but this doesn't seem to have helped either.
Is the battery fully charged. It's the most obvious reason I can think of

Eonon GA2170

Anyone else have this HU?
Uses the RK-PX5 octocore 1.6ghz processor.
Android 8.0 Oreo, 4G RAM, Octa-core & 32G ROM, Split Screen and PIP Multitasking
Had mine for about a month, and really like it
Thinking to get it. I currently have GA2162. Just wondering how quick wifi signals are on it? Considering it has no external wifi antenna like GA2162.
I was concerned about that as well. Seems to pick up WiFi just as good as my GA2160 did. All the Xfinity wifi going down the road it grabs. Much more responsive as well.
Can u confirm it's really on 8.0 ?
Thanks mate. I’m going to order it tomorrow.
I just got this model. Like it so far but just a few things I want to change.
Any luck with doing anything with the home screen? or modifying it in general?
I am looking to change the home screen apps to something besides the preinstalled ones. and change the ugly ass clock.
I a trying to remap the NAVI button to something other than google maps.
Thanks
very dim screen, brightness set to 100%

Hi, anyone who had this unit suffers same issue as mine, very low brightness, dim LCD screen, unpleasant to view in most time of the day, otherwise versatile in function, anyone know the issues or how to fix it, change firmware or hardware?
how this is compared to the similar faced pumpkin HU : AE0273B
Looks identical tome, and why one is 60 dollar more than the other? screen brightness ( different grade of light source, different wifi chip, etc....) Any one can afford to buy two of them and make a compassion review?

I asked the very question of pumpkin on amazon and this is what they replied
"We checked the list of Eonon,and we consulted with our engineer,he informs that the bluetooth and wifi module are different,we use higher chip for this model.
We guarantee that our products and customer service would not disappoint you."
i still went ahead and bought the pumpkin. the screen is fine i added a matt screen protector as for changing the firmware i have been unable to root it and the factory reset only wipes apps and a few settings. not a full return to factory settings (found that out the hard way)
I got mine yesterday. Super responsive. Have not noticed any issues so far. As far as the brightness, my truck is limo tinted, and my radio is at a slight angle. It really does not bug me. I like it overall. I have not tried to root yet, but that is my next step. I can confirm OREO 8 on the unit.

if you manage to get root, please let us know how
The unit is great. Far better than GA2162 but as expected wifi has poor coverage should have given that external antenna as optional.
Anyway can anyone tell me how to stop the HU to kill the app like my camera recording after it comes back from sleep. GA2162 never used to do it.

Hold onto the app icons for few seconds, it will ask to select an app.
No you cannot get rid off ugly ass clock but you can move the main page to end and modify the first page with widgets and icons.
Go to settings >navigation and there will be an option to select an app for navigation physical button.
thanks, f/u the dim screen issue

Great feedback info, should be very helpful for any others who want to buy one of these HU, if I knew these info ahead, I will buy the pumpkin, I did a review atAmazon site to share my experiences. I had a hard time to return it (GA2170, Eonon brand), I did note that pumpkin has the way better Wi-Fi antenna ( before I bought this Eonon while doing the research on both HU), I aslo paid a attention to the other Xtron brand, but I gave that up due to that model didn't have a large physical button, my theory is that, if you use it during driving ( in motion or in darkness), a physical button is way better than the touch feel button ( although flush surface Xtron panel looks cool and better), even I'm minimalist kind of thinking, I still think with large physical button is the way to go ( design) , Both the internal and external mic-phones the Eonon are not flattering at all.

Thanks! regarding the ambient light, mine is Honda fit, much lighter than yours ( bright ) But that's not my issue, I personally found, even during cloudy ( with flurries the weekend in NE) days, it's uncomfortable to view, by view, I mean you watch some photos/videos, not just their app screens ( where they did a greater contrast icon design and the fonts does look clear to me, in any condition except direct sunlight. ).
I tried Youtube videos, ( CNN news, etc), I tried DVD quality movies ( Kill the messenger and Fast and furious 6), in cloudy and around sunset days (weekends), very disappointing, .... I don't wish to have more bad words to bad-mouth any sellers, I'm just trying to tell what I felt and want to know what other users have and think.
I even asked myself, could these type android HU is designed for its multifuction, only, not really for imaging/video displaying, cause you're driving ( in motion), not sit in a couch to enjoy a movie night ( in a 7'; TFE lcd screen). the fundamental design is for information display ( like GPS, BT phones calls) not for entertainment. In another word, I should not expected such HU for that kind of purpose, but I what I though is that I want use it while I'm waiting for someone ( eg, airport pickup, after school , activities pickups) while in a stop condition. I won't watch video during driving ( in motion), plus all manufactures advertise their HU for such entertainment.

Totally agree......
I road around today and I did notice at times the screen being hard to see. I put n youtube, and videos were hard to see at noon. Sux, I love the unit. Needs more contrast. At night, it is perfect.
Hello. I have installed this unit today on my alfa147. Is all ok also the dab+ kit. I have only 2 problem. The dimension of the display borfer that dont put perfectly in my double din chassis and i cant use the gsm dongle because oreo see the usb but i dont have the 3g menù in the configuration.
Cpu and display ok. Very beautiful the split screen with navigator and radio.
After some test, i have found some problem...
1 - The display, with sun, is not bright
2 - After every reboot, i lost my wheel command configuration
3 - My USB 3g Dongle is not compatible with Oreo and i must do the root for install PPP Widget for use it
I have send a message to eonon via messenger and they send me the link for a firmware upgrade EONON-px5_8.0_kld10_ota_20180131.rar
Now i try this one but probably i install the Malaysk Custom ROM , but i'm not sure because this rom is too younger.
has anyone already installed this rom on this hu?
Multiple reviews for the Pumpkin unit mention that their Google login information was stolen, and one mentions Google Play debits against their account.
For those with this unit - do you have any issues with the top bezel obstructing the notifications bar at the top of the display?
the head unit has worst wifi ever and Bluetooth sometimes messes up too. Anyway, anyone knows how to prevent it from killing the background running apps after it comes back from sleep?

Haven't had any issues with mine other than constant power and switched power were reversed on the adapter harness. WiFi is as good as my GA 2160 was with the external antenna, and no issues with Bluetooth... Actually better than my old one!

Yes, I had the same issue and I wrote a similar review on Ebay and Amazon sites to warn the potential buyers to look deeper before buying, we may say that their HU dimension is not up to ISO standard, sub mm bigger.

very disappointing screen, no scale ( contrast) adjustment, there is brightness level adjustment function, and just 3 weeks, my GA2170 had more issues now, the illumination light flicking every 6 seconds every time I switch light on. quite annoying, and lcd screen will also flick at the same pace, dim, bright, dim, bright. very concerning about protuct's quality now, I'm contact them see what's the bottom of it. (noting if I disable the night mode brightness adjustment in the factory setting, the flicking will be much flaster at interval of every second

Eunavi 2 Din 7'' PX6 4G 64G P11 RK3399

I am thinking of buying new HU becouse my existing Hu from Hizpo PX3 7.1.2 is kinda wired, mostly because none of beetter DVR cams do not work.
So I am thinking of this one
https://www.aliexpress.com/item/32934575168.html?spm=a2g0o.cart.0.0.78b03c00oKlwsb
anyone have experience with Eunavi HU?
It's similar to the one I have, it has a few problems with my Skoda Octavia.
It boots up every time it powers up taking about 20seconds.
The canbus doesn't work with all the steering wheel buttons.
The default apps are rubbish
The theme is shocking and you can't read the text properly.
Short of the power on issue, it's not too bad.
i see.. original rom I had on hizpo px3 had similar issues, like power up it was even longer.. but with hal9k rom or "malsik" that changed.
I'm still waiting on eunavi sending me the firmware so I can have a look at fixing the problems.
It's not a problem with it booting up each time, trust me.
I have a dash which goes into standby mode and it drains the battery in about 3-5 days of not using the car for a decent drive. I'm forever having to use jumper cables on the battery. I've since installed a switch, although you can use a relay - to make it boot up every time.
I've just bought this unit btw. I'll let you know how it goes in a month. Hopefully it can be modded.
Hi, how is the unit? Have you had any chance to use rca pre outs? I want to buy an android unit but the only thing stopping me is that Subwoofer preout are either of low voltage or doesn't work at all.
The seller claims its a 5v rca pre out for the sub.. Can you confirm this?

same issue here
So I have the same unit and the same power-problem, takes long to startup every time.
Tried swapping +BATT and ACC but that didn't help the drainage.
Also, mine doesn't hold the radio presets and USB2 doesn't work.
Left a message with Ali-E. to help me with this problem.
My car is a 2011 Dacia Sandero Stepway, which is Renault, basically.
**** solved ******
wire was crossed in the pigtail - radio preset hold, eq.settings hold and lots of other stuff fixed by installing Malays full ROM for PX6/STM32
have autI have autoradio android vw Eunavi I need the secret numbers to open the settings and the habit of adjusting the factory.
