Yt9213a (8227L) NextRadio app can't access FM radio reciever - Android Head-Units

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.

Are there any good FM radio apps?

I have just ordered an S160 unit and from the pictures, I am not sure that I like the radio app - Are there any other good ones that can be downloaded?
Thanks!
There is a mod called "rally" style or something. There are no other apps other than the one from the manufacturer because its specifically written for the radio receiver hardware.
But some people have managed to mod the app appearance somewhat but most have just changed color themes. They are all listed in the first post of the HuiFei thread under modified apps.
This is probably the one most different from the stock layout:

Tunein Radio is one of the best IMHO, always a clear channel and supports local and worldwide presets. Car mode is nice for easy touchscreen navigation and low light at night.

He meant FM radio

Yea, Tunein isn't radio - it's Internet streaming.
Do any of the radio apps allow direct frequency entry, or some other way to easily tune to a particular station? The one on my HuiFei-type unit, you can press on the frequency, but fat fingers make it had to get an exact frequency.

Caixi 9” inch android 8.1 HU FM radio problems

I have this HU and my fm radio reception is very poor.
Already tried normal antenna and amplified antenna but nothing works.
When i try old radio its just fine.
Someone have a solution or another fm tuner offline app.
Its an android 8.1(go) system so i cant download any apps on usb or sd because it can t find the files.
I've had 3 Chinese head units already (on different cars) and they all seem to have this problem

FM Radio keeps scanning for stations

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.

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.

Better firmware or app for my SC9863A unit

Hi guys, i have a Hizpo (Chinese) head unit with SC9863A with basic factory fw (details in screenshot). It is basically doing what it is supposed to do, however i cant find any way to get the traffic assist function to work.
FM Radio app is working, but when i want to listen to music player (or use navi or any other app), it will not interrupt it with traffic announcement from radio station. Unit of course has the TA function. The option is there in the radio app, looks like it is working, but in reality it is not.
I think that just the radio app isnt able to be shown on top of another app (music, navi...). However there is no such option in settings. Or maybe the fm radio app is just useless.
Is there any good app for my unit, which can replace original fm radio app? I have found the NavRadio app here, will that get the job done? Or maybe, is there any fw which i can use instead of the original one? I can imagine that the unit will work better with some better firmware.

This is not a FYT unit. I will request to have it moved to the general Android head units sub-forum
