I have just installed this unit in my car. It is really great.
Android 6.0.1, 1024x600, 2gb ram...radio tda7786...
But...
Have some issues with fm radio. On frequencies where should be only one station i hear two. For example on 92.7, 103, 104.5 fm i hear proper station but in the backgound i can hear station from 101.7.
How to fix that?
I found radio settings... What for are fm local and dx numbers?
And the second qestion is... How to root that device?

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.
Hi,
I have one of the cheap Chinese Android 9.0 headsets with the PX6 Octa-core Processor 1.5 GHz RK3399 (Radio Chip NXP 6686). The model is Fongent Car Android 9.0 Radio Multimedia Player PX6 4G RAM 64G ROM.
The problem I have with it is that the radio will not stay on any station that I choose. Everytime, I switch to a programmed station, it starts to scans after like 10 second and always stops on the first station in memory that it had found. It is getting very annoying now. I tried to fiddle around with the AF TA PTY settings but that didn't do anything.
Anyone has experience with this radio app? Is there another one I can use that doesn't need internet connection to use and can use the antenna?
Please help!
Thank you.
Somewhere in the radio settings you must also select the correct region: japan/europe/etc.
Did you do that?

Yep, i had to do this on mines when i first got it. it was still set to China. Also if you flash the wrong MCU file it could also cause this issue.

I didn't flash anything. The unit is as it came from the factory. I did change the region to US. The radio has automatically programmed different stations under P1, P2, P3, etc all the way to P18 I think. But always stops at 88.7 New station. Even if I choose a different station like P5 or whatever...I get to listen to that station for like 5 seconds or whatever and then it starts to scan and then stop at 88.7! So frustrating. To the point, I just want to use a different FM app for this. But I don't know of any that uses the FM radio to broadcast instead of looking for an internet connection. I am not looking for internet radio.

It happened to me with some radio stations, I solved the problem by turning off the TA.
First question did you contact your seller about this? When you do get to listen to a station does it sound clean? Are you moving or parked? Can you manually tune in or enter a station frequency and see if it starts to scan again? It's possible your car has an amplified antenna and it needs a power injector. Otherwise I'd say something is wrong with the radio and you should send it back.

No I did not contact the seller in China about this. Yes the station sounds clean and clear. I have tried it while parked and/or moving. It doesn't make a difference. Yes I can manually move the tuner to a different station and it plays for a few second and then again starts to scan. It does NOT stay in a particular station other than 88.7. Everything was ok with the stock stereo that came with the car. Is there only on radio app on Android 9.0? Can I not try a different radio app to see if that work? Mailing the unit back would be more hassle that it is worth. To me it is a software issue or some settings/tweaks that needs to be made.
Well I understand that shipping back to China is less than ideal, but your seller is better placed to help you than any of us especially with the little bit of information you provided. Best case they can give you an MCU update that could fix the problem or at the very least work with you to adjust settings in the service menu. Or they may realize the MCU is defective and send you a replacement. The only alternative radio apps I know of are only for MTC MCU. Yes the radio chip is controlled by the MCU so you're not likely to find a generic radio app.
Hello everyone,
I am very new to this world. I bought a Chinese Head Unit for my 2015 Santa Fe. The install was flawless: Canbus worked great for backup camera and steering wheel controls.
I have an issue with the stock AM/FM Tuner. It has FM RDS. I live in Canada, but there is no Canada region. I have tried Europe, Japan, United States and they all present the same issue.
When I turn on the vehicle and the radio starts, it plays the last station I had listened to. The display shows whatever I had the preset button or what was playing the last time I had the radio on. (Kind of a frozen display)
The RDS does not update station or current song playing. The only way to "fix" it is to move the tuner off station and then back to the station. Then the RDS 'wakes up'.
I hope the explanation made sense. Does any one else have an issue?
I am at work right now, but if you need more details I am happy to provide them when I get home.
Thanks for reading this.
I was looking for a different radio app, since the built-in one isn't very good and does not store stations persistently. I downloaded NextRadio, but when it loads it says "FM Radio is Unavailable...... NextRadio doesn't have access to the FM radio receiver in your device". How is it that the stock Radio app works but not this one? Anyone have a good radio app that uses the FM tuner? (Not internet radio). Thanks.

The radio chip in these units is not presented to the Android system. Instead the radio app sends commands to a dedicated radio module on the amplifier board. The same for the Bluetooth unit, as it's not actually part of the Android tablet.
These head units are two devices that work together. The Android part is basically a tablet that has dedicated apps to talk to the Radio part. The two parts work separate, and that's why all the FM radio apps and stuff are such garbage. They have to send commands to the actual FM module on the Radio board and get back a response about what is happening. In theory it would be possible to see what commands and data the FM radio app uses and write your own to send & receive the same data.

Is this separation of modules also related to why the EQ/Balance/Fade functionality does not work on this head unit? I noticed a few reports stating the same problem I'm having... where the faders have no effect whatsoever. No front/rear fade, no left/right pan, and no EQ change.

By the way, I discovered something today... I was playing music files from a USB drive and lo and behold, the EQ and Balance functionality worked. I started to think about why and I think it has to do with what you said. The reason it wasn't working for me initially is because I was trying to use it with the radio, and since u said the radio is outside of the android layer, that's probably why it wasn't working. But it looks like it DOES work with any audio that's within the Android layer.
Can confirm what @pizzaboy192 has posted. You will NOT be able to use any sound processing, not even to mute radio during navigation directions because of this funky implementation.
All you can do is root and then replace the radio apk with the macnaughty one that does save stations and (for me) has HD information.
I used this
https://forum.xda-developers.com/android-auto/android-head-units/everything-yt9216b-t4007063
BTW :you probably miss the HIFI flag in build.prop as in my case at least the built in equalizer and spatializer work with the radio app.. Viper4Android however, does not work, despite being complied in and having root access, simply because the audio path from the radio bypasses the OS.
Hi. I will buy a new android head unit.
Receiving radio frequency without interference. Which device should I buy that captures FM frequencies well?
Or which is the best radio chip.
My car's original tape had the best FM performance
İ want high performance tuner.
