Heater rear window causes radio static? - Android Head-Units

I didn't notice this when I first installed the head unit, however whilst driving yesterday I switched on the heated rear window and the radio audio filled with white noise. The radio reception isn't fantastic (it wasn't fantastic with the previous OEM radio either really), however I am fairly sure the rear heated window shouldn't cause this much interference? Is it an grounding issue?
I have a 2nd generation Tonghai Create unit that came with a fakra to 'standard' antenna input (see attached image).
Cheers
Andy

I would make sure you have a good ground, maybe add a new ground to a screw on the metal chassis of the unit to a factory ground lug on your vehicle.

Using the video in on Joying sofia 2-din unit

I have split my reversing camera with a "Y" cable so one feeds the normal reversing camera in floating socket so it works like a normal reversing camera-it starts up when reverse is engaged, the other I have plugged into the Video-In socket on the rear.
I want this because I have in the space of 12 months had 2 new cars written off by other idiot drivers, luckily I had a dashcam with front and rear cameras which plainly showed I was blameless, even stationary for the first accident.
I vowed never to buy another new car as the trauma of losing my babies is just too much! So I got an old VW EOS, a 2007 model, and there is nowhere to fit a rear camera in this hard-top convertible.
The only app that I have so far found to work with this arrangement is the "AUX" stock application-this works well, but it captures the audio channel too so the radio and music applications are muted.
Has anybody come across an app which can monitor this Video-In socket-they all seem dead set on usb cameras.
Cheers, Tony.

The custom ROM has the right camera app that supports this. Video only.
Why don't you get the camera that fits in the VW emblem??

Thanks for this, do you know the name of the app please?
With the number plate camera, it is:
a) far easier to fit, especially as my rear mudguard is cut where my removable tow-hitch sits, wiring is a doddle.
b) The emblem camera it sits so high, my wife's cat would probably not be visible, it has a habit of sitting just underneath the mudguard.
c) Much less expensive.

Eonon GA9180a review and questions

Recently installed a GA9180a for my 2010 Chevy
runs really nice out the box, start up time is around 20 seconds or less
i'm getting some serious electrical interference noise once the car is started and increases with rpm, if the car is off I do not hear it, I believe this is a known issue with the fm antenna adapter. I bought a fm antenna noise filter to fix this hopefully.
ok google commands work well, I was wondering if theres a way to make phone calls, if I tell google to call...it will not dial out just show a phone logo with the contacts name, has anyone been successful with this?
also, want to remove the wire so while reversing audio will not be cut out, i think its an orange wire
anyone know of the standby mode as well, so the unit does not shut off completely when off?
also, need help with and looking to add my OEM GM reverse camera and have to splice into lines
looking to use the stock GM male mini USB adapter to connect to the back of this unit, so the usb in my center console can charge devices
To the poster above me, theres a setting under the CAR category to enable audio while reversing - you shouldnt need to cut any wires.
I bought this same head unit back in may and im just now getting around to installing it into a 2010 silverado without the factory bose option. The instructions that came with it are a joke. On bluetooth only, theres alternator whine thats easy to hear at higher volume levels and BT audio causes the pillar tweeters to clip/crackle/cutout at certain frequencies. This is more pronounced on rock music with drum cymbals, like most five finger death punch tracks. Funny thing is, that completely goes away when listening to the FM radio or any of the apps on the device like spotify. This is tolerable since the only thing i use BT for is making calls through my phone. Phone calls are not so demanding in the quality department and honestly i can live with it.
What im having the worst luck with is the backup camera. Ive got a backup camera hooked to it using the included 'cam' yellow RCA connector. Ive only connected it for testing at this point and with it getting a solid 12v supply right off the battery, its not working with the head unit. The head unit successfully detects reverse and switches to the camera display, but the screen stays black and theres a yellow diamond with an exclamation point at the center of the screen. Switching to any other gear or back to park returns the head unit to whatever screen it was on before. I checked the camera on another screen and it displays fine. Prior to that, I checked the inline fuse and replaced it just to be sure. Ive already gone through the settings in the head unit itself, video while moving is turned on.
Ive read/seen other people with similar head units (joying, etc) having to disconnect an 'orange wire' from the back of the head unit to get backup video to work correctly. HOWEVER, there are only 2 wires going to my head unit that are orange, one is orange/white and handles illumination while the other is orange/black and handles the reverse signal from the vehicle itself. I disconnected the orange/black wire just to see if that was it. It was not. With this wire disconnected the head unit no longer detected when the vehicle was in reverse and the screen never changed when i put the vehicle into reverse.
At this point im thinking theres gotta be a firmware bug, hardware failure on my particular unit or im doing something wrong. The vehicle-radio harness that came with it is plug and play. The camera itself connects with a single RCA plug and has a positive and negative lead for battery power. I dont know WHAT could possibly be connected incorrectly, but its a theory.
My ask here is if anyone has experience with this head unit, or with eonon head units in general. Does anyone have a clue how i could solve this backup camera problem?
FYI:
there is a can bus decoder in the 'plug and play' vehicle-radio harness, disconnecting it causes the head unit to not wake up when the truck turns on.

I just got my unit also and have the exact same problem as you with the reverse camera, also like you i found lots of talk about cutting the orange wire however I wasn't game to do this yet but it seems like that is not the solution.
it sounds like you guys have a OEM back camera and if your backup camera video shows on rear view mirror check this link:

If your backup camera shows on old OEM radio system, check this link

I did some research but I didn't try it yet. I have backup camera on rear view mirror.
Rear DVD Controls/ DVD Player on 2010 Chevy Avalanche
I recently installed the Eonon GA9180a in my 2010 Chevy Avanlanche with Bose and Rear DVD, first I’m also getting a lot of interference from the radio when the WiFi and Bluetooth are on, wondering if a installing a noise canceling module will fix this? Also I seem to have lost the functions of my rear controls for the DVD players, I’m also wondering if anyone has figured out if this unit allows to watch a movie in the back (rear seat) while listening to music in front main unit?
not sure what you mean by installing a noise cancellation module, i had this unit and I never got the interference noise to go away, I switched a Xtrons unit and it worked well for a couple of months but then the screen went out. I got a replacement but now im getting the same noise interference
Sorry I was talking about a Automotive Noise Suppressor of some sort, just wondering! I really like the deck and features but there are some limitations!
GA9180A
Did you ever get your backup camera to work with the GA9180A?
I have tried it with the regular purple wire "CAN IN" supposed to be "CAM IN". I have tried it as AUXILIARY. I can't get the damn thing to work.
I installed a pumpkin brand in my buick and I had to build my own harness and I got it working first try. This eonon plug and play unit is not working.
If you have it working could you please let me know how. It would be awesome with pictures.
I have the factory bose. I found that ebay instructions were better than Amazon instructions.
They have the purple "CAN IN" plugged into a video out. I don't know why. I would assume that a large number of people are installing a camera and would need to connect the CAM IN into the RCA coming from the camera.
This is the most frustrating install ever. The amazon seller doesn't understand I want a working backup camera.
Eonon says it should work. Nothing more.
Thanks,
Chad
I own a 2013 Silverado with the same radio. The fix is simple.
Engine noise fix.
Take about 6 inches of copper wire. Wrap it around the Sub rca (Blue) coming out the back of the harness and ground it to a screw on the radio. (I drew a red line in the picture showing how to fix it)
If your camera is not working you might have it in the correct rca but the harness might be in the wrong place. the camera wire harness fits into 2 spots on the back of the radio. make sure you put it in the correct slot. look at the picture i posted for your engine noise issue and the correct spot for the harness.
GonzoBean what kind of radio did you have before? if you had a cheap factory radio the basic one chevy gives there is a little more work to get the backup camera to work. Thats if you have a factory backup camera already installed that goes to the mirror. you need to tap into the signal.
**Edit**
2nd picture is for proper wire harness install for bose system.
GA9180A
BIG Thanks for the grounding tip and for the diagram. I am installing a new camera so the feed is coming from the new camera, not the existing wiring harness.
I have tried connecting the camera RCA feed to the "CAN IN" eonon typo should read "CAM IN". The headunit detects when I am in reverse and I get yellow ! triangle.
I have tried connecting the camera RCA feed to the "AUX IN" and then open the "AUX IN" app and I get the yellow ! triangle.
I have tried 2 different backup camera's.
Surely someone has installed a new camera to this unit. Eonon has not been helpful.
Thoughts? Ideas?
Thanks,
Chad

This image shows which wire is the rear camera in and where the harness should be plugged into.
Did you hook the camera up? rca from camera to radio. Power to reverse light?
Did you go into car settings on radio? code 126 and make sure rudder is on.
Ill be in and out of here all day. So we can get this problem solved for you.
The camera has power it is connected to backup lights. I tried 2 different cameras.
From your picture I have rca plug 10 connected to my backup camera's rca feed. Why is it necessary to plug 11 to 12, 13 to 14, 15 to 16 or is it?
I have also tried my backup camera feed to the AUX IN and use the AUX IN app also without any luck. I had to wire a power line for that test.
Thanks KidGixxer, I was out of town today, but will check into "rudder is on".
I will let you know what I find about "rudder is on"

Hello. Same issue as the above posters. I made sure rudder was on and still a failed camera feed with the exclamation point triangle.
The option right above Rudder is what you need to check.
Its called "Prohibit Reverse" Make sure that is off.
And make sure your camera mode is set to "F-CAM"

So I put the "Prohibit Reverse" toggled to off which was default to off. With the cam set to F-Cam. I still have the yellow/red/green grid with a blacked out screen when I go to reverse. Anyone else have this same issue?

If you're seeing the green yellow red grid it might be an issue with the camera itself. If the camera was not hooked up you would get a yellow triangle with an exclamation point.

It also does that as well. At random it seems, going back and forth between the grid and the triangle
I haven't got the camera issue as I ended up going with an aftermarket reverse camera, but I have an annoying issue with background noise/static.
It seems to be similar to the computer generated noise that cheap/early sound cards had in the background. It's enough to be noticeable if the car is idling and the volume is very low.
It doesn't get worse with speed, it is just a constant background static that seems to be computer generated.
I tried wrapping some shielding around the audio cables, but this made no difference. Grounded the headunit directly to the chasis with copper wire, made next to no difference.
Any ideas on the noise would be appreciated.
To the people that still have camera issues. are you using the factory camera that came with your vehicle. Or an aftermarket brand. If its aftermarket the camera might be bad. or bad wiring.(Did you wire the power source to the reverse light and not the brake light. also the camera wont turn on if you e brake is engaged.)
If you are using a factory camera you cant go by the wiring that the manual that comes with the radio says. It wrong. you will need to get a rca cable and cut one side and tap into 2 wires by the bcm near the gas/brake pedals.

That only helps with engine noise.
Turn off Bluetooth and WiFi on the radio and you will hear that the static is gone. There is currently no fix for this.
We were discussing this in this post.
This post to be more specific.
We were looking into rerouting the wires inside this radio. The Bluetooth wire is taped to the top of the am/FM receiver and the WiFi wire route near it as well.
I was going to redo the wiring in my radio but haven't had the time.

Unfortunately the noise on my unit seems unrelated to Bluetooth or WiFi.
I'll keep digging.

Removing interference

Just thought I’d do a quick write up of how I have today got rid of a bit of interference noise/alternator whine I had on my Audi A3 with Bose and a PX5 Android 8 unit.
It wasn’t a massive nuisance but when the volume was down and you revved the car you could hear it through the speakers.
On the Audi forum everybody that has the Bose system and one of these Chinese android units seemingly gets this problem, some people use noise filters or noise suppressors which does get rid of the problem but it also reduces the quality of your sound.
So today I had some ferrite filters laying about that I had previously bought for something else and thought I would use them on the power cables to the headunit. The A3 has a quadlock connector and then obviously there is the loom that comes with the headunit to plug into the quadlock connector from the headunit.
I used 3 of these ferrite filters altogether. One on the yellow cable from the battery, one on the acc cable and one on the ground cable. I have placed these on each of the cables directly behind the connector that plugs into the headunit so I have placed them on the cables before they split off to other sources.
I then rested the unit back in the dash and started the car and I have perfect sound and have lost no sound quality, if anything it is now better as there is no interference.
If you’re not sure what a ferrite filter is then just type it into eBay or something, they just clip onto the cable and have a magnet inside which draws out the interference and are very cheap. You might have seen them before on power cables or some company’s use them on hdmi cables.
I’d advise anyone to try this that has any alternator whine with one of these android units and especially if you have a factory fitted amp and sub like the Bose ones.

I bought a pack of these from Amazon. In addition to putting one on BATT, ACC, and GND, I sprinkled the ferrite beads onto entire wire bundles and audio signal wires like it was Mardi Gras. The sound was not noticeable when the head unit was sitting on the dash as I installed the beads, but it was there when I reinstalled it into the dash. Still RPM-dependent.

Hey,
I have the same problem. Tried the ground loop isolators - the interference is gone but no bass at all. The ferrite filters didn't work. Does anyone have solution for this ?
Thanks
Hello, sorry for bringing back an older thread but I am currently working to fix this issue myself.
I had alternator whine to begin with and the ground loop isolators sorted that but mfilip, I have no bass at all and the sound quality isn’t all that great.
I have tried some Line-Out Converters and they did nothing but make the problem worse. I am going to get some Ferrite Cores and try them too.
The Bose system worked spot on so I know it’s capable, but something just isn’t right. However years ago I retrofitted an RNS-E in place of an Concert head unit and had this alternator whine, it turned out this was because the Bose pin was not connected correctly. Once I moved this pin to the correct location it worked perfectly, but I can’t seem to understand what to do with this pin with the android head unit as there is no where for it to go?

PX5 weird buzz from rear speakers

I have a joying 4gb/32gb unit for chrysler/wrangler that i just installed a few weeks ago. I have been loving it but suddenly today the rear speakers are making a weird buzzing. When i mute the audio it stops. It happens in z-link and the native radio app. I did recently disassemble it to add rear video monitors but dont have them hooked up yet. Any ideas what is causing and how to fix? It isnt low either its a low buzz and it comes and goes.
If the unit has WiFi built in, that's usually the culprit. Try to move closer to the router or turn off WiFi if you're not using it. Otherwise it might be ground feedback, Walmart has these noise isolation type things that slide on/clip to the wires near the speaker. They're basically just magnets, so you might find something around the house you can use to save the trip. Make sure the radio antenna is firmly pressed in the unit and isn't loose on the car body. Check all your grounds for loose wires or add a braided ground cable from the unit body to a metal component in the dash that is grounded to the chassis "BE CAREFUL NOT TO interfere/ obstruct or otherwise use anything near or connected to any airbag components" and if you cut and spliced the original wiring instead of using an adapter, check your speaker polarity at the unit and make sure you've matched the impedance of the speakers to the unit.

possible bad ground?

Have a newer MTCE with rk3399. When I initially installed this unit it was great as I powered the speakers from the built in amp. However after adding sub-woofers I then needed to upgrade mids and highs. I added an amp and now I get an intermittent buzz from front Right channel. i know its not cable interference or even dirty power as i have tested this on a bench as well. if you jiggle the unit (or more specifically the plug with the audio RCAs) the noise will go away. And vice versa . This is the second unit with RCA level outputs that are dirty so im wondering if there is anyone else having issues running an amp from the 4 main RCA audio outs?
Looks like you have found the source of your problem. I can't say my unit has that problem but I will tell you it's not surprising to find cold solder joints on those Chinese units. The problem is the way they get soldered components with large pins don't get hot enough to make a good joint. Just reheat the RCA pins with a soldering iron and add a little bit of solder.
just got done doing just that. going to put her back in my Jeep this evening. ill give the RCAs a little wiggle and see if i get my buzz.
