Joying bad radio reception - Android Head-Units

Hello,
I have a sofua unit of joying mcu 202.04.03 jy
The unit is connected in a 2015 outlander. The radio reception is very poor. Radio reception go on and of in certain areas that stock radio works well
I read in joying forum that there might be a faulty power antenna wire voltage.
Does anyone have solution for this or encounter this?

Then stay with that thread as it also explains which wire to use.
Otherwise: did your previous unit use a (builtin) antenna/signal amplifier? This would mean you need it now as well.

Thank you, have checked this and add a signal amp, the radio lose signal , did not have this problem with klyde unit before , maybe radio app or an update will fix it?

No, I don't think so. Note that there is a radio chip in your unit and it has nothing to do with the Android layer. The MCU firmware makes sure "everything" is received in the radio app, which is technically only a graphic shell, and the MCU sends the button actions back to the chip.
It might be an MCU issue, but if it is simply loss of signal, I guess it is in the radio chip, the connector, the cable or the signal amplifier inside the cable.

Joying JY-UL135N2 Radio App No Sound

Need help... I've searched but cannot find my issue or been able to piece together a solution from all the information available..
I did find on other models when radio is not working, you can go into "Factory Settings" and select a different radio and that fixes the sound. On my unit, I do not have a "Factory Settings" option..
Sound works on everything else but radio has no sound and no stations..
Joying JY-UL135N2
5.1.1
Intel Atom QuadCore 2GB DDR3
MCU Version 2017-02-16
If you have no stations it means that you don't receive anything and that's the reason you have no sound either.
So:
Is your antenna connected?
Do you need an antenna amplifier?
Do you perhaps have a broken antenna cable?
No. Stopped suddenly. Don't know if there was an update. No static (bad reception). Nothing at all from radio.
I am having the exact same issue on a Seicane head unit in my Ford Explorer.
The radio app just stopped producing sound one day but everything else works.
I know it is Android 8.0 but I am not with the vehicle at the moment to give anymore specifics.
Hi.
Did you solve this radio problem?
I have same problem joying JY-UM135N2, no radio sound, no hiss.
I have no luck to find factory settings where to select radio chip.

no AM reception, but good FM reception - wrong radio region?

Apologize if this is the wrong forum to post this in, but I just installed an Android 8.1 head unit in my car in the USA, and I get great FM reception, but I can't get reception for any AM stations. I disconnected the unit and reconnected my old radio to make sure nothing had changed in the car, and I still got good FM and AM with the old radio, so I know the antenna is good.
Is there a setting in the radio for region (USA, Europe, China, etc) that could affect this? When I scan stations, it seems to be in the right range of frequencies, but doesn't stop on any, and I can't manually force it to a station that I know (950). Instead I can make it go to either 945 or 954. I have searched through all of the menus that I can find, and can't find anything that would allow me to see or change the region.
Thanks in advance - Paul
Update on this issue - I was able to get to the menu to change the radio region:
Car Settings:: About the Device (passcode 8888):: Radio
It was defaulted to Europe - I changed it to America 1 and America 2 which at least allowed me to directly tune to a couple of strong AM stations that I know, but I still had no reception. Everything else about the unit works well. I am trying to get them to send me a replacement thinking it is something in the hardware, but please let me know if anyone has any other ideas on things to check.
I have this problem too. Great FM reception, VERY poor AM reception. I've tried all country codes (Australia is not available). I've asked vendor for a solution. Still waiting.
Did you get a solution?
I had this too until I realized that my car has a built in car antenna amplifier (most cars now do) and it needs to be powered. Without power to it, you'll barely get reception. So I connected the antenna amplifier to the powered antenna output from the head unit and that improved it some, but still it wasn't great. Then I checked the voltage from that wire I found that the head unit only puts out 10.6 volts instead of the required 12. So I hooked the power antenna to the same 12V power coming from the car that feeds the head unit and presto, now I get normal radio reception like I used to.
This constantly amazes me, why do so many people not understand about the aerial amplifiers used on most cars now? When you swap out a manufacturer specific unit, make sure all the wires are connected, they're there for a reason!
yes, but most people don't realize that the lead from the head unit that says ANTENNA is not suitable to power the antenna. You must use the 12V power supply coming from the car to power the antenna amp.
It varies with the head unit, many do put out the full battery voltage on the antenna feed wire (ours does) but obviously some don't, your fix is correct for those that don't. The issue is that everyone seems to just leave the amplifier wire disconnected and wonder why it doesn't work.

I know this is an old post but I'm having this issue.
I'm actually little confused as to how to remedy this.
Any help would be appreciated.
Should I splice the blue ant wire into the power wire going to the radio?
I was under the impression the blue ant wire was for people who had a power antenna that raises and lowers when the radio is powered on.
Here's the radio I got for a 2005 Corolla.

The ANT wire of the head unit is intended as power supply for the car antenna. Not only the automatic extending antennas need a power supply, also active antennas.
So it depends on your installed antenna if you need to connect it.
Some active antennas doesn't have a separate wire for power supply. In this case you need a "Phantomeinspeiseadapter" (Google it). Espacially cars from VW group (Skoda, Seat, VW, Audi...) need such an adapter in combination with a 3rd party radio.
The idea is to power the antenna only if it's needed (your listening to radio).
Alternatively the antenna could get its power from the ACC wire. In this case the antenna gets power as soon as you turn on the ignition.
The B+ wire should never be used to power the antenna because this would drain your cars battery 24/7.

Joying Intel AM/FM Radio Issue

So I just installed this unit in my 2002 sierra
https://www.joyingauto.com/joying-8...een-car-navigation-system-with-4g-module.html
AM and FM radio were working fine.
Drove around for about an hour. Came back to my vehicle later on radio worked for about 10 seconds and now my radio just makes a humming sound like something is turning off and on. I took the radio out, rechecked my connections (I connected the Antenna CONT wire to my blue antenna wire, and even tried switching it with the AMP cont wire). I have turned on the setting of ANTENNA ON in the unit options.
What could this be? My bluetooth and music work just fine, it is only the radio. My truck doesn't have a visually retractable antenna, but it does have an onstar antenna, so maybe it technically it is a "power" antenna. Regardless it was once working and now is not. I have emailed JOYING, and their help in broken english is useless. I have had this radio for 1 day and its already malfunctioning. I had a pumpkin px5 in my last truck that glitched here and there, this is just unacceptable on day 1. Not to mention this single din unit doesn't even click into place within the single din radio chassis/housing....
I am attaching a google drive video so that you can hear the humming I am talking about.

As a guess, sounds like the tuner has failed.

Is that something I can fix through software or taking apart the unit? Or will I have to exchange for a new one?

Android TS-4G Opel insignia Tuner 7786AF-3

Hi guys, I have a Android head unit called TS-4G and drive an Opel insignia. (This one https://a.aliexpress.com/_vdJ8NX ) - how can a find out which hardware platform it is?! I think it’s very similar to the px5
I replace the original radio with the Android one, but the radio signal is worst. Dump sound, no signal, no AF. I put a amplifier between the radio and my two car antennas, connected over fakra connectors. The amplifier is powered up with 12v (phantom) with amp I have very low signal, without nothing, so I decided to put my Orginal Radio back in. Now i look why is the signal so bad. I opened the Android head unit and check the reciever. There is a 7786AF-6 build in. Now is the question, replace it with a 6686 or not... ?! Or, how can i improve the signal strength.
Btw. gps, canbus, steeringwheel remote, LTE works nice. Only the fm tuner sucks...
Here some informations about this head unit

Exactly same unit here. Cause bad fm/am signal receiption I gave up and installed a dab+ dongle with new active shark roof antenna. It supports GPS, FM/AM and DAB+ . GPS, FM/AM has good signal receiption now, but DAB is not working well. There are some device interferences, too and I have to check the cables at back side again.
Btw, the PX5 headunit was much better.... (I've got an accident with my opel astra h )
I have a dab+ usb module too, but with a window antenna. In my location in middle germany i have with this antenna worst signal too. 100 meters good signal, next 100 no signal...
How you replace the orginal shark antenna? The orginal shark is in my case the gps one. How you connect gps, and fm with this one antenna? New cables to the antenna, or can use the old one?

some parts in the trunk that can prevent the roof lining from lowering must be removed. otherwise it is almost impossible to access and loosen the screw on the antenna. it's a very fiddly business, I couldn't loosen the screw on my antenna on my own and had to go to a workshop (and I really do a lot on cars.)
The original gps cable can be used again with the new antenna, for fm / am and dab a new separate cable must be pulled forward to the glove compartment. adapters may be required on the radio and dab module.
all in all, it is quite doable, but takes a lot of time. the biggest problem is loosening the old antenna and ensuring that there are no kinks in the roof lining. and make sure to disconnect the battery before converting.
But, it is possible to change the hardware (7786 to 6686 tuner?) the 2nd one is an digital fm tuner - pin out and size are the same. I read on some another threads, that ppl swap these fm tuners...

Car radio app

Hi, does anyone know what radio app supports vordon ac-8290 nexus. I don't seem to find one that works. Rds would be a bonus, if it is even possible.

As always: Radio is placed on the main board and Android is just some sort of "monitor" for it and reacts on system internal communication. There is mostly no other radio app which will work with your main board. May be you can try https://forum.xda-developers.com/t/...9-intel-ts10-uis7862-and-ts18-uis8151.4024701 if your unit is supported.
Thank you for your reply, but sadly it doesn't work.

Well, but this is not FM/AM, it´s another source. Other that DAB+, he could use as example any Online radio application.... but this does not change the bad FM reception...

Most of the time there is something wrong with the antenna connection.
VW, Audi... with diversity:
If your car has multiple antennas like VW, Audi.... you need to make deeper changes to get a good FM reception, because these units do not support diversity. In this case, you need to search a car shop who is able to disconnect the diversity module and connect one single antenna to the unit. In this case you need to get a good antenna amplifier to get this working.
If your car has no deversity:
These cars have an antenna amplifier which needs just a phantom power adapter to get in between the Radio and the antenna, connected to the amplifier cable of your unit. If there is no, just add it to the cable which is marked as ACC.
DO NOT CONNECT IT TO THE CABLE MARKED WITH BAT!
These adapters are really cheap. Don´t buy the cheapest for $5, look for a known supplier.
Before doing anything else, try that out and report back.

Hi, thank you for your reply. I just ordered tha dab+ usb and will try that out. Its not that the FM radio doesn't work, its just the stock radio app is not good, that is why I was looking for an alternative, preferably with RDS and AF which this one does not have, also there is no customization and so on.

In this case you should look for DAB-Z.
This app is hosted in here and the best you can use.... and it´s free.
